摘要: Abstract A self-consistent mean-field investigation is done to test the model accuracy, dependence, and dependence on different parameters in study of superheavy nuclei. This within models-the Skyrme-Hartree-Fock-Bogoliubov (HFB), Relativistic-Hartree-Bogoliubov (RHB) with density-dependent couplings. systematic comparison made experimental data, as well macro-microscopic Finite Range Droplet Model(FRDM). The bulk ground state properties microscopic structure Z=120 nuclei are investigated. Further α-decay series for five isotopes 292,298,299,300,304120 spontaneous fission account number before starts. data available energies half-lives produced reasonably. RHB NL3* parameter set, ImSahu UNIV2 formula calculate found be best suited accurately predicting
