采用基于形变Woods—Saxon势下的推转壳模型理论和处理对力的Lipkin—Nogami(LN)方法,研究了^187Tl的形状共存问题.在自洽条件下,通过求解推转的LN方程得到了原子核总的位能面(TRS)图,证实了在^187Tl核中的形状共存现象,得到了与实验一致的结果.
The shape coexistence in ^187 T1 is investigated with TRS method and the single - particle energies are obtained from deformed Woods - Saxon potential with the Lipkin - Nogami treatment of pairing. The total energy of configuration is obtained by solving the LN equation. The experimental results are reproduced well in the TRS calculation and the shape coexistence in ^187 T1 is confirmed by theoretical calculation.
