论文摘要
在周期性图表中，Z $ <$ 82研究了变形对两蛋白（2p）放射性半衰期的影响。通过采用我们新提出的半经验公式来估算2p-decay的半衰期，其中核变形已以现象学的方式纳入。公式的鲁棒性被证明是因为它非常准确地估算了测得的值，因此可靠地应用于预测其他可能的2p发射体。对于许多富含质子的核，对于衰减能的实验数据不可用，我们使用了使用相对论均值场（RMF）方法从我们的计算中获得的理论值。通过机器学习（ML）技术，理论衰减能量值中的不确定性最小化。探测了2p-射射作用与2P-HALO的相关性和变形。我们的计算显示了几个2p发射器中形状共存的现象，其中发现岩体的形状在基态中更为主导。
Effect of deformation on half-life of two-proton (2p) radioactivity is investigated across the periodic chart for nuclei with Z$<$82. 2p-decay half-lives are estimated by employing our newly proposed semi-empirical formula wherein the nuclear deformation has been incorporated in a phenomenological way. Robustness of the formula is demonstrated as it estimates the measured values quite accurately and, hence, reliably applied to predict the other possible 2p-emitters. For many proton rich nuclei for which experimental data on the decay energies are not available, we have used the theoretical values obtained from our calculations using the relativistic mean-field (RMF) approach. The uncertainties in the theoretical decay energy values are minimised by machine learning (ML) technique. Correlation of 2p-radioactivity with 2p-halo and deformation is probed. Our calculations show the phenomenon of shape coexistence in several 2p-emitters, wherein the prolate shape is found to be more predominant for the ground state.
