In the present work, we systematically investigate the proton radioactivity half-lives of spherical proton emitters adopting a generalized liquid drop model (GLDM) with 16 different proximity potentials, of which the proximity potential Prox.77-13 gives the closest results to the experimental data. Combined with the previous conclusion that the GLDM with proximity potential Prox.77-13 can also best describe α decay half-lives, which makes the model more uniform and consistent. Further, we use the proximity potential Prox.77-13 in GLDM to predict the proton radioactivity half-lives of 14 spherical proton emitters that are allowed energetically but not yet observed experimentally or specifically quantified. Finally, we research the Geiger−Nuttall law for proton radioactivity. The results reveal that the Geiger−Nuttall law can also be well used to study the proton radioactivity half-lives of isotopes with the same orbital angular momentum l.

在目前的工作中，我们系统地研究了球形质子发射器的质子放射性半衰期，采用具有 16 种不同接近电位的广义液滴模型（GLDM），其中接近电位 Prox.77-13 给出了与实验最接近的结果数据。结合前面的结论，具有邻近势Prox.77-13的GLDM也可以最好地描述α衰减半衰期，这使模型更加统一和一致。此外，我们使用 GLDM 中的邻近电位 Prox.77-13 来预测 14 个球形质子发射器的质子放射性半衰期，这些发射器在能量上允许但尚未通过实验或具体量化观察到。最后，我们研究了质子放射性的盖革-纳托尔定律。结果表明，盖革-纳托尔定律也可以很好地用于研究具有相同轨道角动量l的同位素的质子放射性半衰期。
