【Abstract】 Collective state space truncation causes a difference between particle and hole representations. By taking the midshell ¹²⁰Xe as an example, the problem as well as the dependence of the difference on parameters are studied within the framework of microscopic approach based on boson expansion and the MJS substitution. The phase transition in the energy spectrum structure from vibrational mode to γ——unstable mode for Xe isotopes is also studied.更多还原
