Abstract

A gamma gamma angular-correlation experiment has been performed to investigate the low-energy states of the nucleus Mo-98. The new data, including spin assignments, multipole mixing ratios, and lifetimes reveal evidence for shape coexistence and mixing in Mo-98, arising from a proton intruder configuration. This result is reproduced by a theoretical calculation within the proton-neutron interacting boson model with configuration mixing, based on microscopic energy density functional theory. The microscopic calculation indicates the importance of the proton particle-hole excitation across the Z = 40 subshell closure and the subsequent mixing between spherical vibrational and the gamma-soft equilibrium shapes in Mo-98.
