Abstract

A systematic study of alpha and cluster decay of superheavy element with Z = 114 in the mass number range 269 < A < 339 is presented using the models such as coulomb and proximity potential model (CPPM), generalized liquid drop model (GLDM) and temperature dependent dynamical cluster model (DCM). The possible isotopes of superheavy element with Z = 114 are predicted by comparing alpha and cluster decay half-lives with that of spontaneous fission. In the present study, investigations on 284–289Fl reveals that the studied half-lives were found to be good agreement with available experimental values. This study identifies that the nuclei 274–289Fl are having alpha decay half-lives of the order of 10–6 to 10–1 s and these superheavy nuclei can be detected if synthesized in the laboratory.

269–290 Fl超重核的衰变特性

摘要

使用库仑和邻近电势模型(CPPM),广义液滴模型(GLDM)和温度模型,对质量数269 < A <339中Z = 114的超重元素的alpha和簇衰变进行了系统的研究依赖动态集群模型(DCM)。通过将α和团簇衰变半衰期与自发裂变的半衰期进行比较,可以预测Z = 114的超重元素可能存在的同位素。在本研究中,对284-289 Fl的研究表明,所研究的半衰期与可用的实验值高度吻合。这项研究确定了274-289 Fl原子核的α衰变半衰期约为10–6至10 –1 s,如果在实验室中合成,则可以检测到这些超重核。
