摘要
In this study, we have investigated the alpha-decay chains of even even superheavy nuclei Z = 120 in the range of 290 <= A <= 304. The Hartree-Fock-Bogoliubov model is used to calculate the binding energy of these superheavy nuclei. We have included the so-called SkP skyrme function as an effective force and the quadruple deformations. The semi-empirical formulas are used in the reproducing alpha-decay and spontaneous fission half-lives of these superheavy nuclei. By studying the decay chains of the Z = 120 isotopes and comparing them with the half-lives of spontaneous fission, it is predicted that the elements (278)114, (284)114, (274)114, (282)116, (280)116, (290)116, (292)116, (284)118, (294)118 and (292)120 are more stable than the neighboring isotopes in their parent alpha-decay chain. The corresponding neutron and proton numbers represent magical behavior that is in agreement with the numbers predicted before. In this range, the predicted nuclei are found to have large enough half-lives to synthesize them in a laboratory.
