B(E2) anomaly in $6^{+}$ isomers of ${}^{134-138}$Sn isotopes and neutron single-particle energies beyond N=82

Bhoomika Maheshwari, Ashok Kumar Jain

Isomeric studies in neutron-rich nuclei present a powerful tool to explore the structure at the nuclear extremes. We recently used the shell model calculations with Renormalized Ch…
