提出了一种混合模型，该模型结合了构型相互作用（CI）计算的核结构部分和三体方法的发射动力学。通过使用 CI 振幅对三体模型的部分半衰期进行归一化，我们可以很好地重现所有已知的实验二质子 ($2p$) 发射半衰期，但 $^{67}\mathrm{Kr}$ 除外。出于本文的目的，在我们的混合模型中分析了通过实验已知半衰期和 $2p$ 发射分支比的原子核的实验 $2p$ 放射性数据。
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.
