The phenomenon of proton emission from nuclear ground states limits the possibilities of the creation of more exotic proton rich nuclei that are usually produced by fusion-evaporation nuclear reactions. In the energy domain of radioactivity, proton can be considered as a point charge having highest probability of being present in the parent nucleus. Conclaves et al.¹ studied the two-proton radioactivity of nuclei of mass number A<70 using the effective liquid drop model. Delion et al.² reviewed the theories of proton emission to analyse the properties of nuclear matter. Maglione et al.³ analysed the proton emission from the some deformed nuclei. We have studied proton decay in almost all actinide nuclei. We have calculated the energy released during the proton decay (Q_P), penetration factor (P), and half-lives of proton decay. Proton decay half-lives are also longer than that of other decay modes such as alpha decay and spontaneous fission. To check the Geiger-Nuttal law for proton decay in actinide nuclei, we have plotted the logarithmic proton decay half-lives versus 1/sqrt(Q). The competition of proton decay with different decay modes such as alpha decay and spontaneous fission are also studied. We have also highlighted possible proton emitters with the corresponding energies and half-lives in the actinide region.

act系元素质子衰减的系统学

核基态发射质子的现象限制了产生更多奇异的富质子核的可能性，这些核通常由聚变蒸发核反应产生。在放射性的能量域中，质子可以被认为是母体原子核中存在概率最高的点电荷。Conclaves等。¹使用有效液滴模型研究了质量数A <70的原子核的两质子放射性。Delion等。²回顾了质子发射的理论以分析核物质的性质。Maglione等。³分析了一些变形核的质子发射。我们已经研究了几乎所有act系原子核中的质子衰减。我们已经计算了质子衰变（Q _P），渗透因子（P）和质子衰变的半衰期释放的能量。质子衰变半衰期也比其他衰变模式（例如，阿尔法衰变和自发裂变）更长。为了检查the系核中质子衰减的Geiger-Nuttal定律，我们绘制了对数质子衰减半衰期与1 / sqrt（Q）的关系图。还研究了质子衰变与不同衰变模式（例如阿尔法衰变和自发裂变）的竞争。我们还重点介绍了possible系元素区域可能具有相应能量和半衰期的质子发射体。
