本文用一种微观相互作用玻色子模型讨论了Z=64处的能隙对核谱结构的影响以及N=88～90区的核结构相交。结果表明,除n-p相互作用之外,壳模型空间的单粒子能级分布在核结构相交中起了重要的作用。Nd～Dy十六个具体核素的计算结果支持了本文得出的结论。

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 bo- son 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 sp- ectrum structure. For Nd～Dy nuclei the calculations show excellent a...
