Proton radioactivity of neutron-deficient nuclei with atomic numbers Z = 51–91 and mass number 104–211 is investigated using the analytical super-asymmetric fission (ASAF) model — a model used to study α-decay and cluster radioactivity since 1984. The experimental Qp values are compared with calculated ones based on WS4 (Y. Z. Wang et al., 2014–2015), and in few cases KTUY05 (H. Koura et al., 2005) mass models. Proton drip-line and neutron drip-line are determined using the WS4 mass model. We compare the calculated results with experimental half-lives, showing good agreement.

原子序数 Z = 51–91 和质量数 104–211 的原子核的质子放射性

具有原子序数的中子缺陷核的质子放射性Z = 51–91 和质量数 104–211 使用分析超不对称裂变 (ASAF) 模型进行研究——该模型用于研究α-自 1984 年以来的衰变和集群放射性。实验问p值与基于 WS4 (YZ Wang等。, 2014–2015), 在少数情况下 KTUY05 (H. Koura等。, 2005) 大众模型。使用 WS4 质量模型确定质子滴线和中子滴线。我们将计算结果与实验半衰期进行比较，显示出良好的一致性。
