Abstract

Abstract: Semiclasically derived shell structure and pairing correlation energies have been included in the recently developed formula by Royer et al to evaluate the binding energies of several well known α −radioactive nuclei after appending the effects of deformation as well. Exploiting single-particle level density for spherically symmetric harmonic oscillator potential with spin–orbit interactions within the microscopic-macroscopic framework, Q α -values and the penetration probabilities are determined. This method has been extended to several recently detected superheavy elements, experimentally unknown ones and, also to four α −decay chains in Z = 120 isotopes. The obtained results have been compared with the available experimental and theoretical ones. A stability analysis for such nuclei has been done on the basis of the obtained half-lives ( T 1/2 -values) as well.
