Abstract In this study, based on the Wentzel-Kramers-Brillouin (WKB) theory, parameterizing the assault frequency as a function of the decay energy and charge radius of parent nucleus, with the decay preformation factors P_ being calculated through the cluster-formation model (CFM), we systematically investigate the decay half-lives of 559 nuclei from the ground state, including 177 even-even, 277 odd-A, and 105 odd-odd nuclei. The calculated results indicate that our model can effectively reproduce the experimental data, with a corresponding standard deviation of 0. 408. In addition, we use this model to predict the decay half-lives of 70 even-even, odd-A, and odd-odd nuclei with Z = 119 and 120. For comparison, the universal decay law (UDL) proposed by Qi et al. Phys. Rev. Lett 103, 072501 (2009) and the unitary Royer formula (DZR) proposed by Deng et al. Phys. Rev. C 101, 034307 (2020) are also used. These calculated results are essentially consistent.
