Ground‐state properties of heavy and superheavy nuclei predicted by nuclear mass models

摘要: Some nuclear mass formulas are reviewed and applied for the heavy superheavy nuclei. A new formula composed of gross term, even‐odd shell term is also presented. The a revised version spherical basis published in 2000, that is, treated more carefully, considerable improvement brought about. root‐mean‐square deviation from experimental masses 641 keV Z ⩾ 8 N 8. Properties on systematics neutron‐separation energies, alpha‐deacy Q‐values nuclidic region, fusion reaction nuclei compared with some formulas. Furthermore, method estimation fission half‐lives neutron‐rich With this estimation, chart nuclides decays drawn, prediction limit existence region discussed.
