| Abstract | |
An extensive study of alpha-decay half-lives for various decay chains of isotopes of Z = 120 is performed within the axially deformed relativistic mean-field (RMF) formalism by employing the NL3, NL3{*}, and DD-ME2 parameter set. The structural properties of the nuclei appearing in the decay chains are explored. The binding energy, quadrupole deformation parameter, root-mean-square charge radius, and pairing energy are calculated for the even-even isotopes of Z = 100-120, which are produced in five different alpha-decay chains, namely, (296)120 -> No-260, (298)120 -> No-262, (300)120 -> No-264, (302)120 -> No-266, and (304)120 -> No-268. A superdeformed prolate ground state is observed for the heavier nuclei, and gradually the deformation decreases towards the lighter nuclei in the considered decay chains. The RMF results are compared with various theoretical predictions and experimental data. The alpha-decay energies are calculated for each decay chain. To determine the relative numerical dependency of the half-life for a specific alpha-decay energy, the decay half-lives are calculated using four different formulas, namely, Viola-Seaborg, Alex-Brown, Parkhomenko-Sobiczewski and Royer for the above said five alpha-decay chain. We notice a firm dependency of the half-life on the alpha-decay formula in terms of Q(alpha)-values for all decay chains. Further, this study also strengthens the prediction for the island of stability in terms of magic number at the superheavy valley in the laboratories. (AU) | |
