摘要: 对球形核和变形核质子放射性的半衰期进行了系统的分析和研究，提出了新的计算质子放射性寿命的解析公式。 通过对公式计算寿命和实验测量值的系统比较，发现两者之间符合得非常好，说明新公式十分准确并具有良好的预言能力。 Systematic calculations on proton radioactivity halflives of both spherical and deformed nuclei are carried out. A new formula with only four parameters is proposed for proton radioactivity halflives. The halflives calculated by using the new formula are in good agreement with the experimental ones. The new formula is simple but accurate, which is very useful for further experiments.
