Abstract：
Using Wu-Zeng formula to characterize g-band,Bohr-Mottelson formula to describe sband,and introducing a tentative interband interaction,a better description for the yrast,and yrare-band of the most even-even well-deformed nuclei is obtained.The backbending of the moment of inertia is also well reproduced in this formalism.By analysing the parameters used here,other information such as the moment of inertia for the ground state can be concluded.
