Abstract: The onset of deformation in the N=88~90 region and the effects of the gap at Z=64 subshell on nucler structure are investigated in a microscopic approach of the interacting boson model.It turns out that,besides the n-p interaction,the distribution of single particle levels in the shell model space also plays a direct and important role in the rapid transition of spectrum structure.For Nd~Dy nuclei the calculations show excellent agreement agreement with experimental energy systematics.
