A comparative study of αα-decay and spontaneous fission for Z=120Z=120 superheavy isotopes
Abstract
In this study, we have investigated the αα-decay chains of even–even superheavy nuclei Z=120Z=120 in the range of 290≤A≤304290≤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 αα-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 278114278114, 284114284114, 274114274114, 282116282116, 280116280116, 290116290116,292116292116, 284118284118, 294118294118 and 292120292120 are more stable than the neighboring isotopes in their parent αα-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.
