Rotation-driven prolate-to-oblate shape phase transition in 190W: A projected shell model study
arXiv:0711.0260 · doi:10.1016/j.physletb.2007.10.067
Abstract
A shape phase transition is demonstrated to occur in 190W by applying the Projected Shell Model, which goes beyond the usual mean-field approximation. Rotation alignment of neutrons in the high-j, i_{13/2} orbital drives the yrast sequence of the system, changing suddenly from prolate to oblate shape at angular momentum 10. We propose observables to test the picture.
