The evolution of ground-state shapes usually proceeds smoothly, however for Sr and Zr nuclei at N = 60 there is an abrupt shape transition, and very low-lying 0+2 states are observed [1,2]. The dramatic onset of deformation in 100Zr was recently well reproduced in state-of-the-art Monte Carlo Shell Model calculations [3,4], which also predict that the same deformed configuration may coexist at...
The phenomenon of nuclear shape isomerism is an example of extreme shape coexistence in atomic nuclei. It arises from the existence of a secondary minimum in the nuclear potential energy surface (PES), at substantial deformation, separated from the primary energy minimum (the ground state) by a high potential energy barrier that hinders the transition between the minima. Shape isomers have...
