The present study is highlight to address a radioactivity of heavy and super heavy nuclei. We study the nuclear structure effects of the parent nucleus on its half-life times and the preformation of the - particle as a cluster inside it. In particular, both the valence nucleons (holes) and the isospin asymmetry dependencies of the preformation probability of an - cluster inside parents radioactive nuclei are investigated. The calculations are employed in the framework of the density-dependent cluster model of α-decay process for the even-even spherical parents nuclei with protons number around the closed shell Z0 = 82 and neutrons number around the closed shells N0=82 and N0=126.
