Systematic study of cluster radioactivity half-lives based on a modified Gamow-like model

Abstract In this study, taking into account of the contribution of the centrifugal potential on half-life and the effect of electrostatic shielding, we modify the Gamow-like model proposed by Zdeb et al [2013 Phys. Rev. C 87 , 024 308] to systematically investigate the cluster radioactivity half-liv...

Summary:Abstract In this study, taking into account of the contribution of the centrifugal potential on half-life and the effect of electrostatic shielding, we modify the Gamow-like model proposed by Zdeb et al [2013 Phys. Rev. C 87 , 024 308] to systematically investigate the cluster radioactivity half-lives of nuclei ranging from 221 Fr to 238 U. The calculated results can reproduce the experimental data well. Additionally, this modified Gamow-like model is applied to predict the half-lives of cluster radioactivity nuclei whose experimental half-lives have the lower limit. It is found that the predicted results are in good agreement with the ones obtained by using the Gamow-like model and a Viola-Seaborg type formula.
