用B-Splines有限基矢集计算强电场中锂原子的能级

APPLICATION OF B SPLINES TO LITHIUM ATOM’S ENERGY CALCULATION IN STRONG ELECTRIC FIELD

讨论了电场中碱金属原子能级的Ｂ－Ｓｐｌｉｎｅｓ（基样条）计算方法，并采用基样条作为基矢集组成波函数，计算了０～４．５ｋＶ·ｃｍ－１电场中锂原子能级结构．结果与实验符合得很好，这表明基样条方法对强场中原子能级计算具有极大的优越性．根据计算结果。

The B Splines method to calculate energy levels of alkali metal atom in electric field is discussed in this paper.Using a set of basis vectors made up of B Splines the authors formed the wave function and calculated the energy levels of lithium atom in electric field of the region 0～4.5 kV·cm -1 .The results agree with experiments and prove the advantages of B Splines in calculating energies of atoms in strongfield.Theinfluencesof atomic kernel as well as external field to the energy is discussed according to the calculation.
