氦原子1sns组态能量及其相对论修正
Energy and relativistic correction of the 1sns configuration in helium
【摘要】 利用Mathemtica语言开发了一套计算氦原子1sns组态能量的程序.提出了构造氦原子1sns组态波函数的新方法,利用Rayleigh-Ritz变分法对氦原子1sns(n=2—5)组态的非相对论能量进行了计算,并计算了其相对论修正值(包括质量修正、单体达尔文修正、双体达尔文修正、自旋-自旋接触相互作用修正、轨道-轨道相互作用修正),计算结果与实验值相当接近.
【Abstract】 A Mathematica program is developed to calculate the energy and relativistic correction of helium-like atoms in 1sns configuration.A new set of trial functions for 1sns configuration in helium has been suggested.By virtue of the Rayleigh-Ritz variational method,the non-relativistic energies of 1sns configuration in helium(n=2—5) have been calculated,the relativistic corrections,which include mass correction,one-and two-body Darwin correction and spin-spin contact interaction,have been further calculated with the theory of perturbation.The calculated results are in good agreement with experimental data.
