Abstract：
By comparing the values of some quantities obtained in the SD pair truncated shell model and the dynamical symmetries of the interacting boson model(IBM), we identify the nuclear shape phases in the shell model. We study the dependence of the nuclear shape phases on the monopole-pair, quadrupole-pair and quadrupole-quadrupole interaction strength, respectively, in the shell model. We also investigate the vibrational to γ-soft rotational phase transition in the shell model. The obtained results coincide with those obtained in the IBM very well.
