Seniority isomerism in proton-rich N=82 isotones and its indication to stiffness of the Z=64 core

T. Matsuzawa, H. Nakada, K. Ogawa +1

The $10^{+}$ and $27/2^{-}$ isomers of the $Z>64$, $N=82$ nuclei are investigated in the shell model framework. We derive an extended seniority reduction formula for the relevant $E2$…
