Study of isomers in neutron-rich magic ${}^{132}$Sn region

Abstract

Shell model calculations have been done for interpreting two representative isomeric states in neutron rich ${}^{132}Sn$ region using SMN and SMPN Hamiltonians. They are, (i) 2.91 min isomer in ${}^{138}Cs$ and (ii) the 0.57 $\mu s$ isomer in ${}^{136}$Sb nuclei. The results are compared with those obtained with KH5082 and CW5082 Hamiltonians. How the results clearly distinguish the most appropriate interaction has been discussed.
