An improved unified formula for $$\alpha $$-decay and cluster radioactivity of heavy and superheavy nuclei

Abstract

AbstractImproved NRDX empirical formula for $$\alpha $$ α - and cluster decay half-lives is modified by adding the effects of angular momentum, isospin asymmetry and parity. The coefficients are determined using the latest experimental data for $$\alpha $$ α -decay half-lives of 573 nuclei and the available 22 cluster decay half-lives. The modified formulas produced the $$\alpha $$ α - and cluster decay half-lives and agree with calculations of other similar formulas. We used the new formulas to calculate the half-lives of cluster emissions of the SHN with $$Z=120$$ Z = 120 , 122, 124, and 126, which have not yet been experimentally synthesized.
