Approach to the Rotation Driven Vibrational to Axially Rotational Shape Phase Transition Along the Yrast Line of a Nucleus

Yu-xin Liu, Liang-zhu Mu, Haiqing Wei

By analyzing the potential energy surface, the shape phase diagram and the energy spectrum of the nucleus in U(5) symmetry in the IBM, we propose that the U(5) symmetry with parame…
