Phys. Rev. C 21, 664 (1980) - Published 1 February, 1980

Show Abstract

Differential ranges of ${}^{44}{Sc}^{m}$ ${}^{46}{Sc}$ , ${}^{47}{Sc}$ , and ${}^{48}{Sc}$ emitted at 90° to the beam in the interaction of ${}^{238}U$ with 0.8, 3.0, 11.5, and 400 GeV protons have been measured and transformed to the corresponding energy spectra. The mean fragment energies decrease from 83±5 to 58±4 MeV between 0.8 and 11.5 GeV and to 50±3 MeV at 400 GeV. The widths of the spectra increase markedly with energy up to 11.5 GeV and more slowly thereafter. Isotopic differences are minor although the spectra of neutron-deficient ${}^{44}{Sc}^{m}$ are somewhat broader, particularly at 0.8 GeV. The results are compared with the statistical fragment emission model and discussed in terms of asymmetric binary fission and deep spallation mechanisms.

Some dynamical aspects of pickup reactions studied in ${}^{13}C (p, d) {}^{12}C$ at 200-500 MeV

Phys. Rev. C 21, 675 (1980) - Published 1 February, 1980

Show Abstract

Differential cross sections at 22.5° are reported for ${}^{13}C (p, d) {}^{12}C$ to the ground state and first excited state which are characterized as $1 p_{\frac{1}{2}}^{- 1}$ and $1 p_{\frac{3}{2}}^{- 1}$ states. These results on the energy variation and previous ones on angular distributions show a prevailing momentum transfer ( $Q$ ) dependence as has been observed earlier for ${}^{4}{He} (p, d) {}^{3}{He}$ . We discuss this apparent scaling of the ( $p, d$ ) cross section in the variable $Q$ and its implication on the question of the reaction mechanism in comparison with analogous information from other nucleon removal reactions.

Inelastic pion scattering from ${}^{18}O$

T. -S. H. Lee and R. D. Lawson

Phys. Rev. C 21, 679 (1980) - Published 1 February, 1980

Show Abstract

The inelastic scattering of 164 MeV pions from ${}^{18}O$ is studied using the distorted-wave impulse approximation in momentum space. The sensitivity of the predictions to various shell model descriptions of the yrast $2^{+}$ state is examined in detail. The excitation of the triplet of states ( $4_{1}^{+}$ , $0_{2}^{+}$ , $2_{2}^{+}$ ) near 3.7 MeV and the ( $3_{1}^{-}$ , $0_{3}^{+}$ , $0_{3}^{+}$ , $2_{3}^{+}$ ) triplet at about 5.2 MeV are also investigated within the context of the shell model. In order to explain the scattering to natural parity states [those with angular momentum $J$ and parity ${(- 1)}^{J}$ ], one must enhance the theoretical results by about the same factor as needed to explain the $B (EJ); 0 \to J$ transition rates obtained from electromagnetic excitation. The sensitivity of the results to the isoscalar or isovector character of this enhancement is examined. Agreement between distorted-wave impulse approximation calculations and experiment is found to be satisfactory.

$N$ -cluster dynamics and effective interaction of composite particles. I. The dynamical equation

E. W. Schmid

Phys. Rev. C 21, 691 (1980) - Published 1 February, 1980

Show Abstract

A nonrelativistic wave equation for the relative motion of composite particles is derived from a given, microscopic Schrödinger equation. For two composite particles, the theory is identical to resonating group theory. For three and more composite particles it differs by the use of distortion functions with a continuous degree of freedom which allows a correct asymptotic description of the system. The dynamical equation, formally, is a multichannel Schrödinger equation with a matrix of nonlocal and energy-dependent interactions. The internal degrees of freedom of the composite particles and the Pauli principle are incorporated into the interaction. The relative motion wave function of the composite particles is a probability density amplitude in the asymptotic region only. In regions where the composite particles interact, the relative motion function is not a probability density amplitude and may even have a certain degree of off-shell ambiguity. In all regions of configuration space, however, the probability density of particles is defined by the microscopic wave function. The theory is formulated for nuclear fragments but is valid also for atoms and particles consisting of quarks.

Beta decay of ${}^{99}{Tc}^{m}$

D. E. Alburger, P. Richards, and T. H. Ku

Phys. Rev. C 21, 705 (1980) - Published 1 February, 1980

Show Abstract

The emission of $β$ rays from 6.02-h ${}^{99}{Tc}^{m}$ has been detected with an intermediate-image magnetic spectrometer. $β$ -ray components with end-point energies of 434.8±2.6 keV ( $β_{0}$ ) to the ${}^{99}{Ru}$ ground state and 346.7±2.0 keV ( $β_{1}$ ) to the 90-keV state were found with intensities per decay of (1.0±0.3) × $10^{- 5}$ for $β_{0}$ and (2.6±0.5) × $10^{- 5}$ for $β_{1}$ . In the Kurie plot analysis the unique first-forbidden " $α$ " shape was assumed for $β_{0}$ and an allowed shape was assumed for $β_{1}$ . Values of $log f_{1} t = 9.39 \pm 0.11$ for $β_{0}$ and $log f_{0} t = 8.66 \pm 0.08$ for $β_{1}$ were derived. $γ$ rays of 322, 233, and 140 keV were observed in a calibrated Ge(Li) detector with relative source intensities of $I_{322} : I_{233} : I_{140} = (1.13 \pm 0.09) \times 10^{- 6} : (0.95 \pm 0.17) \times 10^{- 7} : 1.000$ . The total $β$ -ray branching of 3.7 × $10^{- 5}$ results in a negligible correction to dosage calculations in the use of ${}^{99}{Tc}^{m}$ for diagnostic nuclear medicine.

Show Abstract

The nuclides ${}^{45}{Ar}$ and ${}^{46}{Ar}$ have been produced by spallation reactions on vanadium targets at $E_{p} = 600$ MeV. The subsequent $β$ decays to ${}^{45}K$ and ${}^{46}K$ states have been studied. An intensity of 98.6 ± 0.6% was measured for the $β$ transition to the 1.94 MeV state in ${}^{46}K$ . A decay scheme involving 13 $β$ branches has been established for ${}^{45}{Ar}$ , and the corresponding $log ft$ values have been deduced. Eleven states are reported for the first time in the $β$ decay scheme of ${}^{45}{Ar}$ at 1.42, 1.47, 1.72, 2.52, 2.57, 2.75, 3.31, 3.99, 4.04, 4.36, and 4.57 MeV. From the lifetime, $τ = 4.6 \pm 0.6$ ns, deduced from $γ - γ$ delayed coincidences, the angular momentum of the 1081 keV level has been established as ${7 / 2}^{-}$ on the basis of the transition strength of its $γ$ decay. A survey on the $1 f_{\frac{7}{2}} \to 1 d_{\frac{3}{2}}$ $M 2$ transition in odd K nuclei is presented and the observed hindrance factors are discussed.

The $K$ -shell autoionization probabilities of ${}^{99}{Tc}$ , ${}^{147}{Pm}$ , ${}^{151}{Sm}$ , and ${}^{204}{Tl}$ have been determined to be (3.52 ± 0.20) × $10^{- 4}$ , (0.936 ± 0.063) × $10^{- 4}$ , (0.024 ± 0.003) × $10^{- 4}$ , and (1.22 ± 0.16) × $10^{- 4}$ , per decay, respectively.

$3^{-}$ - $2^{+}$ first-forbidden beta transitions in the decay of ${}^{72}_{31}{Ga}_{41}$

Phys. Rev. C 21, 728 (1980) - Published 1 February, 1980

Show Abstract

The energy dependence of the beta-gamma angular correlation concerning the outer and inner first-forbidden ( $3^{-}$ - $2^{+}$ ) beta transitions was measured with a fast-slow scintillation assembly. The present results were combined with the other available observables to determine the beta matrix elements, employing the formalism of Bühring. It is shown that the higher-order matrix elements are important in the analysis. From the sizes of matrix elements, it is concluded that a possible domination of $\int \frac{i B_{ij}}{ρ}$ matrix element and cancellation among the vector matrix elements explain the failure of the Coulomb approximation in describing the two ( $3^{-}$ - $2^{+}$ ) beta transitions in ${}^{72}{Ga}$ . The conserved vector current ratio $= \frac{D^{'} y}{x}$ following the present analysis shows a deviation from Fujita's prediction and is consistent with the theory of Damgaard and Winther. A comparison of the features of the two beta transitions reveals similar structure for the levels $2_{1}^{+}$ and $2_{2}^{+}$ in the daughter ${}^{72}{Ga}$ nucleus.

Effective charge in the large $A$ limit

Afsar Abbas and Larry Zamick

Phys. Rev. C 21, 738 (1980) - Published 1 February, 1980

Show Abstract

The isoscalar effective charge correction $e^{0} = e_{n} + e_{p}$ is calculated for a series of $N = Z$ closed shell plus one nucleon from $A = 4$ to $A = 480$ . The results are then extrapolated to large $A$ . A delta interaction - $G δ ({\vec{r}}_{12})$ is used, with the strength $G$ chosen by the "quadrupole condition" that the mean single particle-single hole splitting for the quadrupole state be $2 ℏ ω$ . The effective charge is calculated in first order, in the Tamm-Dancoff and the random phase approximation. The value of $e^{0}$ varies from about 0.5 for mass 4 to 1 for $A \to \infty$ . The value of one is the Bohr-Mottelson result for an $N = Z$ closed shell. We see that in our model this result holds only asymtotically.

${}^{41}{Sc}$ - ${}^{41}{Ca}$ Coulomb displacement energy

N. Auerbach, V. Bernard, and Nguyen Van Giai

Phys. Rev. C 21, 744 (1980) - Published 1 February, 1980

Show Abstract

The Coulomb displacement energy in the ${}^{41}{Sc}$ - ${}^{41}{Ca}$ system is calculated using three different methods. All three methods make use of Hartree-Fock densities at some stage. The Hartree-Fock calculations are performed with the SIII and SIV Skyrme-type forces. The results from all three methods are in agreement with each other. The resulting Coulomb displacement energy is less than 4 or less than 6 percent smaller than the experimental one depending on the force employed. Higher order Coulomb corrections are evaluated and it is found that they can be very large (of the order of 1 MeV) and depend on the approach taken. The use of the analog state defined with the $T_{-}$ operator as a representation of the physical analog leads to an overestimate of the Coulomb displacement energy by more than 0.5 MeV. The inclusion of Coulomb distortion terms restores the result by reducing the Coulomb displacement energy. One can also conclude from the present study that the mechanism of treating higher order Coulomb corrections by taking the giant isovector monopole as the only important intermediate state is in fact the correct one and gives precise results.

Magnitude of energy dissipation in fission

Phys. Rev. C 21, 752 (1980) - Published 1 February, 1980

Show Abstract

It is shown that no definite conclusions can be drawn regarding the magnitude of energy dissipation in fission during the descent from the saddle point, by a comparison of the calculated deformation and interaction energies of fission fragments near scission, with the experimental fragment excitation and kinetic energies. This is contrary to the conclusions drawn by Schultheis and Schultheis on the basis of a similar analysis. The reasons for this discrepancy are also discussed.

Redundant states, reduced potentials, and extra nodes in the radial wave function

B. Bagchi, B. Mulligan, and T. O. Krause

Phys. Rev. C 21, 1 (1980) - Published 1 January, 1980

Show Abstract

First-principle scattering calculations which include antisymmetrization of a projectile with respect to identical particles in the target result in a nonsymmetric nonlocal effective potential. Such a potential can lead to redundant states in the scattering wave function. In this case the potential is required to satisfy a consistency condition. We discuss this condition and the manner in which it can be imposed. We also discuss the replacement of this potential by a reduced symmetric nonlocal effective potential which does not produce redundant states. This reduced potential generates a scattering wave function orthogonal to the redundant states. If the original equation has one redundant state, the phase shift at zero energy is $π$ , resulting in an extra node in the zero-energy wave function. The reduced effective potential must retain this extra node. This characteristic of the reduced effective potential is illustrated with an example. We show that the extra node produced by the potential in the example comes either from a spurious state or a bound state of that potential.
