在自旋极化Xα交换近似下Li原子振子强度的过渡态计算
Transition state calculations of oscillator strengths of atom Li in spin polarization exchange approximation
摘要
为了考虑自旋极化效应,我们修改了Ellis和Goscinski,[Physica Scripta,9,104(1974)]提出的振子强度的过渡态计算方法.应用该方法修改后的形式算得原子Li的基态和(或)低激发间s-p、p-s和p-d等各类跃迁的振子强度f值.计算结果进一步表明,对于某些跃迁说来,使用这一方法所得到的数据甚至比诸如Hartree-Fock方法等那些较复杂的方法算得的数据更接近于列表值. 这一点揭示了过渡态在振子强度计算中的物理意义.
Abstract
The calculation method for transition state of oscillator strength suggested by Ellis and Gosoinski [Physica Scripta, 9, 104 (1974)] has been modified for considering spin polarization. By means of this version, f-values for s-p, p-s and p-d transitions between the ground and or lower excited states in atom Li are obtained. It is further shown that the data obtained by using this method approach the tabulated values better than ones by using some more complex methods such as Hartree-Fook method for some transitions. This may reveal the physical meaning of the transiiion state in calculation of osuillator strength.
