Quadrupole and monopole transition properties of $0^+_2$ in Gd isotopes

Nuclear Theory 2016-04-20 v2

Abstract

The longstanding problem of characterization of the 02+0^+_2 states in Gd isotopes is revisited by adopting the Nilsson++BCS mean field and the random-phase approximation. The interband electric quadrupole transition strengths varying almost two orders of magnitude are nicely reproduced at the same time as other observables. These results indicate that the 02+0^+_2 states, in particular, those in lighter isotopes are well described as β\beta vibrations excited on top of deformed ground states without recourse to the shape-coexistence picture.
