Stability of heaviest atomic nulei in new macroscopic energy model

Theoretical investigations of the stability of the superheavy nuclei is presented. Spontaneous fission half-lives ($T_{sf}$) are calculated in the macroscopic-microscopic approach based on the deformed Woods-Saxon potential. For the macroscopic part a very recently developed Lublin-Strasbourg drop model ($LSD$) is used. In order to minimize the action integral in the large deformation space multi-dimensional dynamical-programing method ($MDP$) is applied. The $\alpha$-dacay half life ($T_{\alpha}$) was calculated by the semi phenomenological Viola and Seaborg relationship with the more recent adjusted parameters.
