Phys. Rev. C 14, 583 (1976) - Published 1 August, 1976

Show Abstract

The level structure of the odd-odd nuclide ${}^{172}{Lu}$ has been studied by means of the ( ${}^{3}{He}$ , $d$ ) and ( $α, t$ ) proton transfer reactions on ${}^{171}{Yb}$ . The spectrum has been interpreted in terms of two-quasiparticle states formed by coupling the transferred proton with the ${1 / 2}^{-}$ [521] neutron in the target ground state. Assignments have been proposed for the bands arising by parallel and antiparallel coupling of the target neutron with protons in the ${7 / 2}^{+}$ [404], ${1 / 2}^{-}$ [541], and ${5 / 2}^{+}$ [402] Nilsson orbitals. Some evidence is also presented for the assignment of the { ${\frac{1}{2}}^{-} {[521]}_{n} \pm {\frac{9}{2}}^{-} {[514]}_{p}$ } levels. The $Q$ value of the ${}^{171}{Yb} ({}^{3}{He}, d) {}^{172}{Lu}$ reaction is measured to be -792 ± 34 keV, yielding a mass excess of -56700 ± 37 keV for ${}^{172}{Lu}$ .

Calculated nucleon spectra at several angles from 192-, 500-, 700-, and 900-MeV ${}^{12}C$ on ${}^{56}{Fe}$

Phys. Rev. C 14, 590 (1976) - Published 1 August, 1976

Show Abstract

Neutron spectra were calculated as a function of angle between 0 and 110° for ${}^{12}C$ on ${}^{56}{Fe}$ at 192, 500, 700, and 900 MeV. Proton spectra were calculated for the same angular range but for only 192-MeV ${}^{12}C$ on ${}^{56}{Fe}$ . The most significant property of these spectra is that there is an appreciable number of neutrons emitted with energies greater than the incident energy per nucleon at all angles investigated.

Phys. Rev. C 14, 596 (1976) - Published 1 August, 1976

Show Abstract

The inverse reaction ${}^{4}{He} ({}^{35}{Cl}, p) {}^{38}{Ar}$ has been used to measure the mean lifetime of the 2.168 MeV, first excited state of ${}^{38}{Ar}$ in six stopping materials. Analysis of the Doppler broadened $γ$ -ray line shapes using scaled experimental stopping powers yielded lifetime values, in ps (for stopping material), of 0.68 ± 0.08 (Ti), 0.68 ± 0.08 (Fe), 0.72 ± 0.08 (Ni), 0.67 ± 0.08 (Cu), 0.65 ± 0.07 (Ag), and 0.67 ± 0.07 (Au) with an average value of 0.68 ± 0.03 ps. A comparison of these lifetime values with those derived using the stopping power tabulation of Northcliffe and Schilling is also presented.

Phys. Rev. C 14, 602 (1976) - Published 1 August, 1976

Show Abstract

High-spin states have been investigated with the ${}^{88}{Sr} ({}^{7}{Li}, p 2 n) {}^{92}{Zr}$ reaction by $γ$ - $γ$ coincidence, $γ$ -ray angular distribution, and pulsed beam- $γ$ timing measurements with Ge(Li) detectors. Decay schemes, level energies, and spin-parity information were obtained for ${}^{92}{Zr}$ from the data. The high-spin states involving the ${(π 1 g_{\frac{9}{2}})}^{2} {(ν 2 d_{\frac{5}{2}})}^{2}$ configuration were identified, with the ( $12^{+}$ ) member being at 4947 keV. Tentative identification of the members of the $(π 1 g_{\frac{9}{2}} π 2 p_{\frac{1}{2}}) {(ν 2 d_{\frac{5}{2}})}^{2}$ configuration has also been made. The observed experimental levels in ${}^{92}{Zr}$ are compared with recent theoretical calculations.

Elastic scattering data are fitted by opticalmodel calculations and the parameters of the potential are determined. The neutron-transfer and protonpickup reaction cross sections are compared with the predictions of the exact finite-range distorted-wave Born-approximation.

Finite-range distorted-waves Born-approximation calculations, which included recoil effects exactly, were performed for the reaction ${}^{13}C$ ( ${}^{3}{He}$ , ${}^{6}{He}$ ) ${}^{10}C$ leading to the $0^{+}$ , ground state and the $2^{+}$ , 3.35 MeV state in ${}^{10}C$ for a bombarding energy of 70.3 MeV. The results of the analysis showed that, contrary to the findings of a zero-range distorted-waves Born-approximation study, this reaction can be interpreted as a direct cluster transfer to both of the final states in ${}^{10}C$ .

Interaction of 2.0-, 3.9-, and 29-GeV ${}^{14}N$ ions with U, Bi, Au, and Ag: Track detector study

S. Katcoff and J. Hudis

Phys. Rev. C 14, 628 (1976) - Published 1 August, 1976

Show Abstract

Fission induced by relativistic ${}^{14}N$ ions was compared with that induced by GeV protons. Although binary fission cross sections are considerably greater with ${}^{14}N$ , most of the increases can be attributed to the larger total reaction cross sections $σ_{R}$ . Ternary fission cross sections increase almost twofold beyond the increases in $σ_{R}$ . With the highest energy ${}^{14}N$ used, 2.1 GeV/nucleon, very little momentum was transferred to the target nuclei in either fission or nonfission events (unpaired tracks); but with the 0.14- and 0.28-GeV/nucleon projectiles there is evidence of considerable transfer in both types of processes. Measurements were made with mica and Lexan track detectors. The results are related to other recent high-energy heavy-ion data obtained by various techniques.

Decay of 39-day ${}^{103}{Ru}$ and 17-day ${}^{103}{Pd}$ to the levels of ${}^{103}{Rh}$

Phys. Rev. C 14, 639 (1976) - Published 1 August, 1976

Show Abstract

The levels in ${}^{103}{Rh}$ have been studied by following the $γ$ rays and × rays emitted in the decay of 39.35-day ${}^{103}{Ru}$ and 17.5-day ${}^{103}{Pd}$ . Several new $γ$ rays have been detected with an anti-Compton spectrometer which allow the assignment of a new level and improved spin assignments. Conversion coefficients for most transitions following the decay of ${}^{103}{Ru}$ have been calculated using the $γ$ -ray intensity values of this work and literature values for the relative intensities of conversion electrons. The conversion coefficient for the 53-keV transition was also determined via the x-ray to $γ$ -ray coincidence method corrected for the $557 γ$ - $53 γ$ angular correlation. The weighted average of both measurements yields the recommended value of $α_{K} (53) = 1.95 \pm 0.13$ which corresponds to an $M 1 + (2.1 \pm 2.0) %$ $E 2$ transition. $B (M 1)$ and $B (E 2)$ values of (0.040 ± 0.001) and (213 ± 76) Weisskopf units, respectively, have been obtained for the 53-keV transition.

Influence of singularities on perturbation theory for the effective Hamiltonian

C. M. Vincent

Phys. Rev. C 14, 660 (1976) - Published 1 August, 1976

Show Abstract

The energy-independent effective Hamiltonian $H (z)$ is considered as an analytic function of the coupling parameter $z$ . It is shown that a point $z_{b}$ is not a singularity of $H (z)$ unless the energy of some state that is selected for representation in the model space ( $L_{P}$ ) coincides, at $z = z_{b}$ , with the energy of a state that is excluded from representation in $L_{P}$ . This result establishes the correctness of previous conjectures by Schucan and Weidenmüller, and implies that perturbation theory for $H (z)$ will generally have a larger radius of convergence than perturbation theory for the individual energies. For the case of a cut ("intruder-state cut") joining an isolated pair of branch points close to the real axis, the singular behavior of $H (z)$ is examined in detail. The residue of the cut is expressed in terms of quantities that can be calculated by diagonalization of a real, symmetric modification ("minimal smoothing") of the Hamiltonian matrix. A formula is given for the contribution of an intruder-state cut to the error incurred by $n th$ order perturbation theory for the physical quantity $H (1)$ . Consideration of a numerical example shows that if the values of sufficiently high orders of perturbation theory are known, the residues of intruder-state cuts may be evaluated. This allows estimation of the errors that intruder-state cuts produce in perturbation theory summed to finite order, and yields a criterion for the optimal truncation of divergent perturbation series.

Hartree-Fock-Bogoliubov calculations with $T = 1$ plus $T = 0$ pairing correlations

T. S. Sandhu and M. L. Rustgi

Phys. Rev. C 14, 675 (1976) - Published 1 August, 1976

Show Abstract

Hartree-Fock-Bogoliubov calculations have been performed for even-even $N \neq Z$ isotopes using the Kuo-Brown reaction matrix elements for the Hamada-Johnston potential. The possibility of generalized pairing is explored by considering $T = 1$ , $T = 0$ and $T = 1$ plus $T = 0$ correlations for the axial and triaxial shapes. It is found that only for the nuclei with $N - Z = 2$ there is a small contribution by the $T = 0$ pairing correlations. Only the $| T_{z} | = 1$ pairing correlations are important for the ground-state solutions.

Four-body bound states from the Schrödinger equation with separable potentials

B. F. Gibson and D. R. Lehman

Phys. Rev. C 14, 685 (1976) - Published 1 August, 1976

Show Abstract

The coupled, two-variable integral equations that determine the four-body bound state, when the interactions are represented by separable potentials, are derived from the Schrödinger equation instead of the Yakubovsky $t$ -matrix equations. The integral equations are solved numerically for simple $s$ -wave potentials without resort to separable expansions of their kernels. For rank-one potentials the $α$ particle is severely overbound. Sensitivity to the singlet effective range and the tensor component of the triplet interaction is discussed.

We describe a test for checking matrix elements of two-nucleon forces between three-nucleon wave functions by a comparison with matrix elements between two-nucleon wave functions. The test can be used to check both analytic and programming work.

Three-body unitary transformations, three-body forces, and trinucleon bound state properties

Michael I. Haftel

Phys. Rev. C 14, 698 (1976) - Published 1 August, 1976

Show Abstract

A three-body unitary transformation method for the study of three-body forces is presented. Starting with a three-body Hamiltonian with two-body forces, unitary transformations are introduced to generate Hamiltonians that have both two- and three-body forces. For cases of physical interest, the two-body forces of the altered Hamiltonians are phase equivalent (for two-body scattering) to the original and the three-body force vanishes when any interparticle distance is large. Specific examples are presented. Applications for studying the possible role of three-body forces in accounting for trinucleon bound state properties are examined. Calculations of the ${}^{3}{He}$ and ${}^{3}H$ charge form factors and Coulomb energy difference with hyperspherical radial transformations and with conventional $N$ - $N$ potentials are performed. The form factor calculations demonstrate how the proposed method can help obtain improved agreement with experiment by the introduction of appropriate three-body forces. Calculations of the Coulomb energy difference confirm previous estimates concerning charge symmetry breaking in the $N$ - $N$ interaction.
