【摘要】 本文在相对论理论框架下,分别在点电荷和两参数 Fermi 核模型近似下计算了高离化态类氢离子(Z=80～112)n=1～ 3壳层的波函数和能级。分析了核有限体积效应对它们的影响。在此基础上,给出了核有限体积效应对原子能级的修正公式。同时,还进一步讨论了相对论效应和核有限体积效应之间的相互影响,发现对高 Z 元素相对论效应与核有限体积效应之间有很强的耦合。更多还原

【Abstract】 Based on the relativistic theory,the wavefunctions and low-lying levels of highly charge states hydrogen-like ions for the shells n=1～3 were calculated using different nuclear model——point-like nuclear and Fermi nuclear model with two parameter,respectively.The influences of the finite nuclear size effects on wavefunctions and level energies were analysed. Furthermore,it was given that a fitting formula related to nuclear parameter a and c in Fermi nuclear model for finite nuclear effects on the atomic level energy.The influence between the relativistic effect and the finite nuclear size effects were discussed. It is found that there is a strong coupling between relativistic effect and finite nuclear size effects for high-Z elements.更多还原
