Nuclear half-lives for α-radioactivity of elements with 100 ⩽ Z ⩽ 130

Abstract

Theoretical estimates for the half-lives of about 1700 isotopes of heavy elements with 100 ⩽ Z ⩽ 130 are tabulated using theoretical Q-values. The quantum mechanical tunneling probabilities are calculated within a WKB framework using microscopic nuclear potentials. The microscopic nucleus–nucleus potentials are obtained by folding the densities of interacting nuclei with a density-dependent M3Y effective nucleon–nucleon interaction. The α-decay half-lives calculated in this formalism using the experimental Q-values were found to be in good agreement over a wide range of experimental data spanning about 20 orders of magnitude. The theoretical Q-values used for the present calculations are extracted from three different mass estimates viz. Myers–Swiatecki, Muntian–Hofmann–Patyk–Sobiczewski, and Koura–Tachibana–Uno–Yamada.
