摘要：
Improved NRDX empirical formula for alpha- 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-decay half-lives of 573 nuclei and the available 22 cluster decay half-lives. The modified formulas produced the alpha- 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, 122, 124, and 126, which have not yet been experimentally synthesized.
