In this work, based on the liquid-drop model and considering the shell correction, we propose a simple formula to calculate the released energy of proton radioactivity (Q p ). The parameters of this formula are obtained by fitting the experimental data of 29 nuclei with proton radioactivity from ground state. The standard deviation between the theoretical values and experimental ones is only 0.157 MeV. In addition, we extend this formula to calculate 51 proton radioactivity candidates in region 51 ≤ Z ≤ 83 taken from the latest evaluated atomic mass table AME2016 and compared with the Q p calculated by WS4 and HFB-29. The calculated results indicate that the evaluation ability of this formula for Q p is inferior to WS4 while better than HFB-29.

基于液滴模型的质子放射性释放能量公式
在这项工作中,基于液滴模型并考虑壳层校正,我们提出了一个简单的公式来计算质子放射性的释放能量(Q p)。该公式的参数是将29个原子核与基态质子放射性的实验数据拟合得到的。理论值与实验值之间的标准偏差仅为 0.157 MeV。此外,我们扩展了这个公式来计算从最新评估的原子质量表 AME2016 中提取的区域 51 ≤ Z ≤ 83 中的51 个质子放射性候选物,并与WS4 和 HFB-29 计算的Q p进行比较。计算结果表明,该公式对Q p的评价能力 不如WS4,但优于HFB-29。
