We perform systematical evaluations of the α decay half lives for 317 nuclei in the area of Z=102-120 in the preformed cluster model (PCM) in order to investigate the dependence of α decay
The interplay of the fundamental forces(here mainly the strong force and electromagnetic force)holds nucleons together to form atomic nuclei.However,in nature onlyless than ten percent of the total number of nuclei
