摘　　要：在宏观—微观模型的理论框架下,采用Nilsson势对Z=116同位素链上原子核基态的结合能、α衰变能和四极形变进行了计算,并把理论计算结果与实验数据和其他理论模型的结果进行了比较和讨论.研究发现,理论计算值和实验数据符合,也与其他模型的计算结果符合.此外,还讨论了Z=116同位素链上的位能曲面和可能出现的形状共存现象.By means of the framework of macroscopic-microscopic model with the Nillson potential, the ground-state binding energies, alpha-decay energies, and quadrupole deformations of nuclei in the Z=116 isotopes are calculated. The calculated results are compared with experimental data and with other theoretical results. It is shown that the calculated results are consistent with other theoretical results and with the experimental data. In addition, the potential energy surface and shape-coexistence are also discussed.
