SHAPE COEXISTENCE EFFECTS OF SUPER- AND HYPERDEFORMED CONFIGURATIONS IN ROTATING NUCLEI .2. NUCLEI WITH 42-LESS-THAN-OR-EQUAL-TO-Z-LESS-THAN-OR-EQUAL-TO-56 AND 74-LESS-THAN-OR-EQUAL-TO-Z-LESS-THAN-OR-EQUAL-TO-92

摘要

This work extends our survey of the high-spin nuclear properties published earlier in ATOMIC DATA AND NUCLEAR DATA TABLES (50, 179, 1992), where the results for 58 less than or equal to Z less than or equal to 74 nuclei were presented. The extension here corresponds to nuclei from the adjacent 42 less than or equal to Z less than or equal to 56 and 74 less than or equal to Z less than or equal to 92 regions. In the latter nuclear range, the effects of super- and hyperdeformation are predicted to be even more pronounced. Total energies are calculated for 123 nuclei in the lower-Z range and 215 nuclei in the higher-Z range for spins I = 0 (ground states), 20, 30, 40, 50, and 60. Calculations are based on the Strutinsky method and the cranking approximation. The results are presented in the form of two-dimensional maps of the total nuclear energy as a function of the quadrupole deformations, beta 2 and gamma, and spin. At each spin value and at each (beta 2, gamma) point the energies are minimized with respect to the hexadecapole deformation, beta 4. The macroscopic energy term in the Strutinsky formula corresponds to the ''folded-Yukawa plus exponential'' formulation proposed by Moller and Nix. The microscopic energy term was calculated using the universal Woods-Saxon approach. (C) 1995 Academic Press, Inc. [References: 30]
