标题： Role of universal function of the nuclear proximity potential: A systematic study on the alpha-decay of heavy/super-heavy nuclei and α-induced reactions

摘要： 通用函数的概念是接近势模型的基本优势。 我们对使用WKB近似方法研究接近势模型的通用函数在250基态到基态跃迁的α衰变过程中的作用进行了系统研究。 为了实现这一目标，将接近势模型中提出的五个通用函数gp 77、Guo 2013、Ngo 80、Zhang 2013和Prox. 2010纳入了Prox. 77的形式中。 获得的结果表明，通用函数的径向行为影响了{\alpha }粒子的穿透概率。 计算了理论上的{\alpha }衰变半衰期并与相应的实验数据进行了比较。 结果表明，Prox. 77结合Guo 2013通用函数对现有数据拟合最好。 还研究了不同通用函数在超重核（SHN）从Z=104到Z=118的{\alpha }衰变半衰期中的作用。 结果表明，使用Prox. 77结合Zhang 2013通用函数可以很好地描述超重质量区域的实验半衰期。 在本文中，还检验了原始和修改后的接近势77的适用性，用于{\alpha }粒子与10种不同的靶核之间的完全融合反应。 我们的结果表明，对于涉及轻核和中等核的反应，使用Prox. 77结合Zhang 2013通用函数可以很好地再现测量的{\alpha }诱导的融合反应截面。 而Prox. 77结合Guo 2013通用函数模型在较重系统亚屏障能量下与实验数据表现出可靠的吻合。 显示英文摘要

摘要： The idea of the universal function is fundamental advantage of proximity potential model. We present a systematic study of the role of universal function of the proximity potential model on alpha decay process for 250 ground state to ground state transitions using WKB approximation. In order to realize this goal, five universal functions proposed in the proximity models gp 77, Guo 2013, Ngo 80, Zhang 2013 and Prox. 2010 have been incorporated into the formalism of Prox. 77. The obtained results show that the radial behavior of universal function affects the penetration probability of the {\alpha} particle. The theoretical {\alpha} decay half lives are calculated and compared with the corresponding experimental data. It is shown that the Prox. 77 with Guo 2013 universal function provides the best fit to the available data. The role of the different universal functions in the {\alpha} decay half lives of super heavy nuclei (SHN) with Z from 104 to 118 are also studied. It is shown that the experimental half lives in the super heavy mass region are described well using the Prox. 77 with Zhang 2013 universal function. In this paper, the validity of the original and modified forms of the proximity 77 potential is also examined for complete fusion reactions between {\alpha} particle and 10 different target nuclei. Our results show that the measured {\alpha} induced fusion reaction cross sections can be well reproduced using the Prox. 77 with Zhang 2013 universal function for the reactions involving light and medium nuclei. Whereas, the Prox. 77 with Guo 2013 universal function model demonstrates a reliable agreement with the experimental data at sub-barrier energies for heavier systems.
