摘    要:
运用推广的液滴模型来确定新核素288115及其α衰变链上核的衰变位垒, 采用量子力学中处理α衰变的WKB方法, 对该链上各原子核的α衰变半寿命进行了研究.计算结果表明推广的液滴模型结合WKB方法可以很好地在超重区符合α衰变半寿命的实验值. 同时把推广的液滴模型的计算结果和采用密度相关的M3Y微观核力的结果做了详细的比较, 宏观模型(推广的液滴模型)和微观模型(密度相关的M3Y微观核力)计算的α衰变半寿命以及实验值三者之间的符合是对新核素288115及其α衰变链上核半寿命很好的检验.

关 键 词:推广的液滴模型  WKB方法  超重核  α衰变半寿命

Abstract:
The properties of the nuclei belonging to the newly observed nuclei starting from ^288115 have been studied with the generalized liquid drop model connected with WKB approximation. The calculated results have been compared with the results of the DDM3Y theory and the experimental data. The half lives of this new alpha decay chain have been well tested from the consistence of the macroscopic, microscopic and the experimental data.
Keywords:generalized liquid drop model   WKB approximation   superheavy nuclei   alpha-decay half-time
