Evidence of oblate-prolate shape coexistence in the strongly-deformed nucleus 119Cs

Evidence of oblate-prolate shape coexistence in the strongly-deformed nucleus 119Cs

Prolate-oblate shape coexistence close to the ground state in the strongly-deformed proton-rich A≈120 nuclei is reported for the first time. One of the four reported bands in 119Cs, built on a 11/2− state at 670 keV, consists of nearly degenerate signature partners, and has properties which unequivo...
