Nowadays,the study on the deformation of heavy nuclei and super-heavy nuclei (SHN) is a hot subject in nuclear physics.A number of heavy nuclei and SHN around 270Hs have already been

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
