Abstract—

We have studied proton radioactivity of heavy nuclei of atomic number range 72 < Z < 88. We have calculated the energy released during the proton decay (Q_P) and half-lives of proton decay. To study the competition between different decay modes, we have compared the proton decay half lives with that of the decay modes such as alpha decay, beta decay, cluster decay and spontaneous fission. To check the Geiger–Nuttall law for proton decay, we have plotted the logarithmic proton decay half-lives versus 1/sqrt(Q). We have also highlighted possible proton emitters with the corresponding energies and half-lives in the atomic number range 72 < Z < 88.

原子序数范围72 <Z <88的重核的质子放射性

摘要—

我们研究了原子序数范围为72 < Z <88的重核的质子放射性。我们计算了质子衰变（Q _P）和质子衰变半衰期释放的能量。为了研究不同衰变模式之间的竞争，我们将质子衰变半衰期与阿尔法衰变，贝塔衰变，团簇衰变和自发裂变等衰变模式的半衰期进行了比较。为了检查Geiger–Nuttall定律的质子衰减，我们绘制了对数质子衰减半衰期与1 / sqrt（Q）的关系图。我们还重点介绍了可能的质子发射体，其相应的能量和半衰期的原子序数范围为72 < Z <88。
