论文摘要
考虑到父核中两个发射质子的预性概率，我们将库仑和接近电势模型（CPPM）扩展到系统地研究接近质子滴管线的细胞核的两种放射性半衰期。选择的接近潜力是代理。 81 Blocki等人提出。此外，在1981年，我们应用了该模型来预测可能的2p放射性候选者的半衰期，其2p放射性在能量允许或观察但尚未在评估的核特性表Nubase2016中进行量化。预测的结果与其他理论模型和经验公式的结果非常吻合，即有效的液滴模型（ELDM），广义液滴模型（GLDM），类似游戏的模型，Sreeja公式和Liu formula。
Considering the preformation probability of the two emitted protons in the parent nucleus, we extend the Coulomb and proximity potential model (CPPM) to systematically study two-proton (2p) radioactivity half-lives of the nuclei close to proton drip line. The proximity potential chosen is Prox. 81 proposed by Blocki et al. in 1981. Furthermore, we apply this model to predict the half-lives of possible 2p radioactive candidates whose 2p radioactivity is energetically allowed or observed but not yet quantified in the evaluated nuclear properties table NUBASE2016. The predicted results are in good agreement with those from other theoretical models and empirical formulas, namely the effective liquid drop model (ELDM), generalized liquid drop model (GLDM), Gamow-like model, Sreeja formula and Liu formula.
