摘　　要：采用投影壳模型(Projected Shell Model,PSM)方法计算了98,100Sr同位素基带的能量并与实验结果进行了比较,同时也研究了98,100Sr同位素基带的跃迁能量以及运动学和动力学转动惯量.研究表明,在98,100Sr原子核基带中出现的全同跃迁实验现象在理论计算中得到了很好的再现,充分说明了这两条转动带在低自旋时为全同带.The projected shell model（PSM） approach was performed on calculating the energy levels of the ground bands in 98,100Sr isotopes and the calculated results were compared with the experimental data.Moreover,the transition energies of ground band,kinematic and dynamic moment of inertia were investigated by our PSM calculations.The good agreement with the experimental results indicated that the identical transition in ground band in 98,100Sr isotopes observed in experimental work was reproduced well by the theoretical calculation which could confirm the identical bands emergence in low spin region.
