摘　　要：采用尼尔逊势的宏观-微观理论系统研究了最近合成超重核294118及其α衰变链的基态性质.给出了这些原子核的结合能、α衰变能和寿命,重点讨论了这些原子核的α衰变能.将计算结果与实验结果和其他理论模型作了比较,发现计算结果与实验数据符合较好,也与其他模型的结果接近,表明宏观微观理论模型对超重原子核基态性质的描述是可靠和有效的.The ground state properties of nucleus ^（294） 118 and its a-decay chain are systematically studied by the macroscopic-microscopic （MM） model with the Nilsson potential. The binding energies, α-decay energies and deformations are calculated and emphases are placed on the α-decay energies. The calculated results are compared with available experimental data and theoretical results from other models. The calculated results are very close to the experimental data and other theoretical results. This shows the validity and reliability of MM model in studying the ground state properties of superheavy nuclei.
