Theoretical study of alpha decay based on Woods-Saxon potential

Alpha decay properties of superheavy nuclei are investigated within the Unified Fission Model based on a Modified Wood-Saxon potential. In a first step, the predictive power of the model was confirmed in the region of heavy and super-heavy nuclei using different mass tables. The present model was subsequently applied in Z = 120–130 region. The computed alpha decay half-lives are compared, on the one hand, with those obtained in the framework of the Coulomb and proximity potential model and, on the other hand, with the spontaneous fission half-lives.
