Microscopic Particle-Core Coupling Calculations: Application to Heavy Odd-Odd and Odd-Even Sb Nuclei

摘要

We have carried out a fully microscopic description of particle-core coupling calculations on heavy-odd-mass Sb nuclei. Using a shell-model description of the core system (Sn nuclei) and a separable multipole-multipole (lambda=2+3) proton neutron interaction, we have derived the particle-core coupling expressions (applicable for odd-mass as well as for odd-odd nuclei). Detailed calculations are carried out for exp 130 Sb, exp 129 Sb (and the corresponding core nuclei exp 129 Sb, exp 128 Sn). In the latter case, extensive comparison is made with a macroscopic particle-core coupling description. We also discuss in some details the similarities and differences of the microscopic core E2 matrix elements and the quadrupole boson cfp coefficients. (Atomindex citation 12:583647)
