Ground-state inversion: The monopole-force governance in neutron mid-shell region

This study analyzes the evolution of single-proton states within the odd-A isotopes of 117−133Sb. We identified the monopole force interaction between the πg7/2 and νh11/2 orbitals as the key driver of the ground-state inversion observed in 121Sb. Moreover, we provide an additional asset for this mo...

description This study analyzes the evolution of single-proton states within the odd-A isotopes of 117−133Sb. We identified the monopole force interaction between the πg7/2 and νh11/2 orbitals as the key driver of the ground-state inversion observed in 121Sb. Moreover, we provide an additional asset for this monopole force by investigating the negative-parity states in 132Sb and demonstrating its manifestation through a comparative assessment of πg-νh multiplets. Our results provide conclusive evidence, for the first time, explaining the ground-state inversion in 121Sb through observations in 132Sb. The increasing occupation and configurations of the orbit πd5/2 revealed that the single-proton property of state 5/2+ remained robust even in the neutron mid-shell region.
