Abstract

A hybrid model is proposed which combines the nuclear structure part from configuration-interaction (CI) calculations and the emission dynamics from a three-body approach. By normalizing the partial half-lives from the three-body model with CI amplitudes, we can reasonably well reproduce all known experimental two-proton ($2p$) emission half-lives, except for $^{67}\mathrm{Kr}$. For the purpose of the present paper, the full body of experimental $2p$ radioactivity data for nuclei for which the half-life and the $2p$ emission branching ratio are experimentally known has been analyzed in our hybrid model.
