Nuclear halflives for αradioactivity of elements with 100 ⩽ Z ⩽ 130
Abstract
Theoretical estimates for the halflives of about 1700 isotopes of heavy elements with 100 ⩽ Z ⩽ 130 are tabulated using theoretical Qvalues. The quantum mechanical tunneling probabilities are calculated within a WKB framework using microscopic nuclear potentials. The microscopic nucleusnucleus potentials are obtained by folding the densities of interacting nuclei with a densitydependent M3Y effective nucleonnucleon interaction. The αdecay halflives calculated in this formalism using the experimental Qvalues were found to be in good agreement over a wide range of experimental data spanning about 20 orders of magnitude. The theoretical Qvalues used for the present calculations are extracted from three different mass estimates viz. MyersSwiatecki, MuntianHofmannPatykSobiczewski, and KouraTachibanaUnoYamada.
