提出了研究质子放射性的简明方法。光谱因子由相对论平均场（RMF）理论与BCS方法（RMF+BCS）相结合得到。在考虑母核结构的基础上，用量子力学方法估计了攻击频率。通过WKB近似计算穿透性。不引入其他参数。将提取的实验光谱因子与RMF+BCS计算的光谱因子进行了比较，结果吻合较好，表明本方法对质子放射性具有较好的计算效果。预测了一些最可能的质子发射，这可能对未来的实验有用。
Concise methods are proposed to study proton radioactivity. The spectroscopic factor is obtained from relativistic mean field (RMF) theory combined with the BCS method (RMF+BCS). The assault frequency is estimated by a quantum mechanical method considering the structure of the parent nucleus. The penetrability is calculated by the WKB approximation. No additional parameters are introduced. The extracted experimental spectroscopic factors are compared with those from the calculations by the RMF+BCS, and the agreement is good, implying that the present methods work quite well for proton radioactivity. Predictions are provided for some most possible proton emissions, which may be useful for future experiments.
