Nuclear rotational current and velocity fields, the cranking model, and transverse electroexcitation of the first excited state of ${}^{12}C$

Mark Radomski

Phys. Rev. C 14, 1704 (1976) - Published 1 November, 1976

Show Abstract

We examine current and velocity fields of rotating deformed nuclei. Although the harmonic oscillator cranking model gives rigid moments of inertia, the velocity field is not a rigid rotation in the examples studied. Such fields are partially observable via electroexcitation, and we compare ${}^{12}C$ to experiment. A slight improvement in experimental precision would allow different models to be distinguished.

Variational principles for the projected breakup amplitude

Yukap Hahn

Phys. Rev. C 14, 1709 (1976) - Published 1 November, 1976

Show Abstract

Two alternate forms of variational principles for the breakup amplitude describing the two- to three-cluster transition are derived such that all the integrals involved in the intermediate stages are well defined. The first form contains a trial Green's function with which both the initial and final state trial wave functions are constructed. The earlier form of the Kohn-type variational principle derived by Lieber, Rosenberg, and Spruch is recovered, however, when this connection between the trial functions is removed. The second form of the variational principle is derived by projecting out from the trial functions all the open channel components which correspond to the two-cluster structures including the rearrangement channels. The remaining part of the wave functions describes the channels with three-cluster structures, and the integrals involving this part are then mathematically well defined.

$d + {}^{16}O$ and $N + {}^{16}O$ systems with the resonating-group method

M. LeMere, Y. C. Tang, and D. R. Thompson

Phys. Rev. C 14, 1715 (1976) - Published 1 November, 1976

Show Abstract

The resonating-group method is used to study the $d + {}^{16}O$ and $N + {}^{16}O$ systems. A generator-coordinate technique is employed to derive the nonlocal interaction between the clusters. The result shows that, as expected, the calculation yields differential scattering cross sections and polarizations which agree rather well with experimental data. In particular, the scattering behavior at large angles is adequately described. Also, from this study, one obtains information concerning the structure of rotational bands in the compound nuclei ${}^{18}F$ and ${}^{17}O$ .

Decomposition of the smooth cutoff model angular distribution

Phys. Rev. C 14, 1721 (1976) - Published 1 November, 1976

Show Abstract

We discuss and display the pole contributions to the smooth cutoff angular distribution with the aid of the far-side, near-side decomposition of the scattering amplitude. We further show, and illustrate by explicit calculation, that the nuclear amplitude $f_{N} (θ)$ is pole dominated in and somewhat beyond the angular region where $\frac{σ}{σ_{Ruth}}$ oscillates.

Transitions excited in ${}^{10}B$ by 180° electron scattering

L. W. Fagg, R. A. Lindgren, W. L. Bendel, and E. C. Jones, Jr.

Phys. Rev. C 14, 1727 (1976) - Published 1 November, 1976

Show Abstract

Peaks at excitations of 5.11, 6.02, 7.48, 8.90, 10.79, and 11.56 MeV were observed in spectra of ${}^{10}B$ produced by 180° inelastic scattering of electrons at 40.5, 50.6, and 60.6 MeV. The transitions at 6.02 and 8.90 MeV appear to be $E 2$ and $M 2$ or $E 2$ , respectively. There is evidence for $M 1$ transition strength to at least one level in the 11 MeV excitation region. The model-dependent radiative widths of the levels at 5.11 and 7.48 MeV were determined to be: $Γ_{0} (M 2) = (6.9 \pm 1.4) \times 10^{- 4}$ eV and $Γ_{0} (M 1) = 11.3 \pm 2.0$ eV, respectively. Subject to qualifications cited in the text, radiative widths for some of the other transitions are also given.

Pion-gamma angular correlations following inelastic scattering

Martha S. Iverson and E. Rost

Phys. Rev. C 14, 1733 (1976) - Published 1 November, 1976

Show Abstract

Angular correlations between inelastically scattered pions and deexcitation $γ$ rays depend upon the spin density matrix of the residual nucleus and thus provide additional information not available in the differential cross sections. The correlation function is calculated for the $0^{+}$ → $2^{+}$ → $0^{+}$ transition in ${}^{12}C$ and the resulting symmetry angles are found to be quite similar to those obtained in the adiabatic limit. The model sensitivity is tested for medium energy pions by comparing the Kisslinger potential results with those using a local Laplacian potential. Some differences, especially near cross section minima, are found between the different potential models.

Channel coupling and nonorthogonality in elastic and transfer processes

S. R. Cotanch and C. M. Vincent

Phys. Rev. C 14, 1739 (1976) - Published 1 November, 1976

Show Abstract

The direct reaction $A (a, b) B$ is described by exactly solving the Schrödinger equation for a few-body Hamiltonian within a restricted model space. The model space allows for coupling to rearrangement channels by including basis vectors classified according to different mass partitions. The nonorthogonality of basis vectors that correspond to different mass partitions is investigated in detail. A surface approximation is developed to understand the magnitudes of multistep amplitudes produced by channel coupling to rearranged partitions. The surface approximation uses a separable Green's function approximation to the multistep series, and gives a convenient closed-form expression. Finite-range coupled-channels calculations are presented for the reactions ( $d, d$ ), ( $d, p$ ), and ( $p, p$ ) on oxygen and zirconium targets, and for ( ${}^{16}O$ , ${}^{16}O$ ), ( ${}^{16}O$ , ${}^{12}C$ ), and ( ${}^{12}C$ , ${}^{12}C$ ) on silicon and sulfur targets. To assess higher-order effects, these results are consistently compared with lowest-order results using folded distorting potentials. The calculations indicate that the effects of nonorthogonality are small for these reactions, but the light-ion reactions showed much larger effects. Theoretical explanations of the behavior of nonorthogonality and channel-coupling effects are given, and lead to criteria for predicting when such effects may be important. Channel-coupling effects are expected to be important whenever the distorted-wave Born-approximation transfer amplitude is unusually sensitive to the intermediate channel optical potential. Nonorthogonality effects are roughly proportional to channel-coupling effects, but are much smaller than coupling effects except when a small mass is transferred between two large masses.

Normalization and finite-range effects in distorted-wave Born-approximation calculations for ( $d, {}^{3}{He}$ ) and ( $d, t$ ) reactions

N. S. Chant and J. N. Craig

Phys. Rev. C 14, 1763 (1976) - Published 1 November, 1976

Show Abstract

Exact finite-range distorted-wave Born-approximation calculations have been carried out for ( $d, {}^{3}{He}$ ) and ( $d, t$ ) reactions at incident energies up to 80 MeV. It is found that the local energy approximation does not correctly reproduce the energy variation of exact calculations for ${}^{51}V (d, {}^{3}{He}) {}^{50}{Ti} (g . s .)$ between 30 and 80 MeV and, in addition, overestimates finite-range effects for ${}^{16}O (d, {}^{3}{He}) {}^{15}N (g . s .)$ at 80 MeV. The effects of various choices for the range function for ( $d, t$ ) and ( $d, {}^{3}{He}$ ) reactions are discussed. Some new values for the zero range normalization constant are discussed.

Level structure of ${}^{74}{As}$ from the ${}^{72}{Ge} (α, n p γ)$ reaction

G. García Bermúdez, M. Behar, A. Filevich, and M. A. J. Mariscotti

Phys. Rev. C 14, 1776 (1976) - Published 1 November, 1976

Show Abstract

States of ${}^{74}{As}$ , excited through the ${}^{72}{Ge} (α, n p γ)$ reaction at $E_{α} = 30 to 55$ MeV, were studied. Excitation functions, $γ$ -ray angular distributions, $γ - γ$ coincidences, and $γ$ -time distributions with respect to the beam bursts, were determined. Three excited states are identified with states previously observed with the ( $p, n$ ) reaction. In addition, six new levels are incorporated into the level scheme. The decay pattern of these levels is rather simple. The existence of two $γ$ -ray cascades showing quite similar energy spacings and possible spin sequence $J = 7 \to 6 \to 5 \to 4$ which mainly feed the known $3^{-}$ state at 183.0 keV state is observed. A half-life $T_{\frac{1}{2}} = 28 \pm 2$ nsec of a level at 259.2 keV was determined. This is the state whose $g$ factor was previously assigned to a level at 273.8 keV.

Show Abstract

Nuclear properties of the excited states below 3.2 MeV in ${}^{56}{Cr}$ were studied in the ${}^{54}{Cr} (t, p γ) {}^{56}{Cr}$ reaction at $E_{t} = 2.9$ MeV. Reaction-produced protons were detected at 171°±4° to the beam in coincidence with $γ$ rays. $γ$ -ray angular correlations and branching ratios were measured using an array of five NaI(Tl) crystals, while $γ$ -ray energies and lifetime limits were obtained using a Ge(Li) detector. Spin assignments for some of the excited states were obtained in addition to multipole mixing-ratio information.

Show Abstract

Cross sections for evaporation residue formation and fission following complete fusion of ${}^{35}{Cl}$ with ${}^{27}{Al}$ , ${}^{48}{Ti}$ , ${}^{54, 56}{Fe}$ , ${}^{58, 60, 62, 64}{Ni}$ , ${}^{90}{Zr}$ , and ${}^{116, 124}{Sn}$ have been measured with counter telescopes for laboratory projectile energies between 70 and 170 MeV. Elastic scattering of ${}^{35}{Cl}$ + ${}^{58, 62}{Ni}$ has been measured near the interaction barrier. The excitation functions for complete fusion are analyzed with a semiclassical model, and fusion barrier heights and radii are extracted. These data are discussed in terms of the nuclear density overlap and the nuclear potential contributions to the fusion barrier. The results are compared with the predictions of several heavy ion potential models and with parameters for the interaction deduced from elastic scattering data. For the systems with masses $A < 100$ about 70% of the total reaction cross section appears as complete fusion. This fraction decreases with increasing mass of the compound system. Evaporation residue and fission excitation functions have been analyzed by the Bohr-Wheeler model using the rotating liquid drop model of Cohen, Plasil, and Swiatecki. To first order these calculations give a satisfactory description of both sets of results.

Show Abstract

Angular distributions for elastic and inelastic transitions in ${}^{20}{Ne}$ + ${}^{16}O$ scattering have been measured at $E ({}^{20}{Ne}) = 50$ MeV. For the $0^{+}$ , $2^{+}$ , and $4^{+}$ members of the ${}^{20}{Ne}$ ground-state rotational band, the angular distributions exhibit pronounced backward peaking characteristic of an $α$ -cluster exchange mechanism. The analysis of the ground-state transition in the first-order elastic transfer model yields no satisfactory fit although microscopic cluster form factors and full recoil corrections are employed. A coupled channels calculation for the $0^{+}$ , $2^{+}$ , and $4^{+}$ transitions reveals very strong coupling effects, indicating that the coherent superposition of first-order optical model and distorted-wave Born-approximation amplitudes may not be an adequate model for these reactions.

Scission-point model of nuclear fission based on deformed-shell effects

B. D. Wilkins, E. P. Steinberg, and R. R. Chasman

Phys. Rev. C 14, 1832 (1976) - Published 1 November, 1976

Show Abstract

A static model of nuclear fission is proposed based on the assumption of statistical equilibrium among collective degrees of freedom at the scission point. The relative probabilities of formation of complementary fission fragment pairs are determined from the relative potential energies of a system of two nearly touching. coaxial spheroids with quadrupole deformations. The total potential energy of the system at the scission point is calculated as the sum of liquid-drop and shell- and pairing-correction terms for each spheroid, and Coulomb and nuclear potential terms describing the interaction between them. The fissioning system at the scission point is characterized by three parameters—the distance between the tips of the spheroids ( $d$ ), the intrinsic excitation energy of the fragments ( $τ_{int}$ ), and a collective temperature ( $T_{coll}$ ). No attempt is made to adjust these parameters to give optimum fits to experimental data, but rather, a single choice of values for $d$ , $τ_{int}$ and $T_{coll}$ is used in the calculations for all fissioning systems. The general trends of the distributions of mass, nuclear charge, and kinetic energy in the fission of a wide range of nuclides from Po to Fm are well reproduced in the calculations. The major influence of the deformed-shell corrections for neutrons is indicated and provides a convenient framework for the interpretation of observed trends in the data and for the prediction of new results. The scission-point configurations derived from the model provide an interpretation of the "saw-tooth" neutron emission curve as well as previously unexplained observations on the variation of $\overset{―}{TKE}$ for isotopes of U, Pu, Cm, and Cf; structure in the width of total kinetic energy release as a function of fragment mass ratio; and a difference in threshold energies for symmetric and asymmetric mass splits in the fission of Ra and Ac isotopes. In spite of a number of recognized simplifications in the model, quantitative fits to the data are generally within expected errors of the shell corrections determined by the Strutinski prescription.

Starting from measured provisional and post neutron mass distributions, the neutron emission curve, $ν (m^{*})$ , is calculated for the photofission of ${}^{235}U$ and ${}^{238}U$ with 25-MeV bremsstrahlung, by applying a method similar to the method described by Terrell. As a test of the procedure, the $ν (m^{*})$ curve for the spontaneous fission of ${}^{252}{Cf}$ and the thermal neutron induced fission of ${}^{235}U$ are also calculated and compared with the directly measured curves. The $ν (m^{*})$ curves show the typical saw-tooth structure, indicating that fragment shell effects play an important role in the photofission of ${}^{235}U$ and ${}^{238}U$ with bremsstrahlung in the mentioned energy region.

Phys. Rev. C 14, 1878 (1976) - Published 1 November, 1976

Show Abstract

We have performed optical-model calculations using the Klein-Gordon and the Dirac equations for the 600 MeV $p - {}^{4}{He}$ scattering experiments of Boschitz et al., and the 1050 MeV $p - {}^{4}{He}$ scattering experiments of Baker et al. We have compared these analyses with our previous analysis of the 1000 MeV $p - {}^{4}{He}$ experiment of Palevsky et al. In comparing the results at the three energies we find that the experiments require a slightly energy-dependent optical potential rms radius. The average value is in good agreement with the ${}^{4}{He}$ matter radius obtained from electron scattering, and substantially smaller than the low energy ${}^{4}{He}$ optical potential rms radius. On the other hand, the experiments require quite different values for the optical potential strength parameters.
