摘　　要：采用投影壳模型(Projected Shell Model,PSM)方法,计算了99Sr核素的基带能量,并与实验结果进行了比较.同时研究了99Sr核实验上观测到的几条边带的能量,预测了几条低激发转动带.研究表明,99Sr核素基带以及边带的能量在理论计算中得到了很好的再现,并且对预测的几条单粒子转动带也给出了相应的组态信息以及带头能量.The projected shell model （PSM） approach has been performed in calculating the energy levels of the ground band in neutron- rich 99 Sr nucleus and the calculated results has been compared with the experimental data. Moreover, a series of side bands energy which include the experimental observation and the theoretical prediction has been calculated by PSM approach in 99 Sr nucleuses. The investigation indicates that the energy levels of ground band and side bands are reproduced well by theoretical calculation, and we obtain the corresponding configurations and band head energy for the predicted single - particle rotational bands. We hope our prediction can provide valuable information for the future experiments.
