E2 collectivity in shell-model calculations for odd-mass nuclei near 132Sn

E2 collectivity in shell-model calculations for odd-mass nuclei near 132Sn

Shell-model calculations for 127,129In and 129,131Sb are presented, and interpreted in the context of the particle-core coupling scheme, wherein proton g9/2 holes or g7/2 particles are added to semimagic 128,130Sn cores. These results indicate that the particle-core coupling scheme is appropriate fo...
