中文摘要：

运用投影壳模型研究了正常形变丰中子核同位素102,104Nb的低能级能谱，并指定了它的准粒子组态，理论计算所得到的能谱曲线与实验给出的能谱曲线非常一致，说明了投影壳模型对研究重核低能级谱非常有效。

英文摘要：

The Projected Shell Model（PSM） is used to study the low energy scheme of the neutron-rich normal-deformed isotopes of odd-odd nuclei 102,104 Nb. The quasiparticle configuration is assigned. The the- oretical calculations of the energy band of 102,104 Nb could well reproduce the experimental data. It is shown that PSM is a valid method for studying the low energy scheme of heavy nuclei.
