“…In 2005, Tavares et al first proposed a phenomenological one-parameter model (OPM) to evaluate the α decay half-lives of bismuth isotopes on account of Wentzel-Kramers-Brillouin (WKB) theory and considering the overlapping effect [48]. Since then, the OPM has been successfully applied to evaluate the α decay half-lives of platinum and neptunium isotopes, and the calculated results can reproduce the experimental data well [49,50]. Recently, Zou et al successfully extended this model to the aspect of proton radioactivity [51].…”

In the present work, based on Wentzel-Kramers-Brillouin theory, we systematically study the clusterradioactivity half-lives of 22 nuclei ranging from 221Fr to 242Cm by using a phenomenological model, which considersthe screened electrostatic effect of Coulomb potential. In this model, there are two adjustable parameters i.e. theparameter t and g, which are related to the screened electrostatic barrier and the strength of spectroscopic factor,respectively. The calculated results indicate this model can well reproduce the experimental data while the corre sponding root-mean-square (rms) deviation is 0.660. In addition, we extend this model to predict the half-lives ofpossible cluster radioactive candidates whose cluster radioactivity are energetically allowed or observed but notyet quantified in the evaluated nuclear properties table NUBASE2020. The predicted results are consistent withthe ones obtained by using other theoretical models and/or empirical formulae including the universal decay law(UDL) proposed by Qi et al. [Phys. Rev. C 80, 044326 (2009)], a semi-empirical model for both α decay and clusterradioactivity proposed by Santhosh et al. [J. Phys. G 35, 085102 (2008)] and a unified formula of half-lives for αdecay and cluster radioactivity proposed by Ni et al. [Phys. Rev. C 78, 044310 (2008)].
