He原子在平行电磁场中的回归谱研究

Recurrence spectra of He atoms in strong external fields

利用包括实散射的闭合轨道理论和分区自洽的计算方法 ,计算标度能量ε =- 0 13,标度电场 F =0 0 1,n≈ 4 0 ,m =0时三重态He原子在平行电磁场中的闭合轨道和回归谱 ,并与同种情况下的氢原子谱做了比较 ,进一步证实了离子实对光吸收过程的重要作用。

Using region-splitting consistent iterative method and taking the core-scattering into account,we found out the closed-orbits and calculated the recurrence spectra of He atoms in parallel electric and magnetic fields at scaled energy ε=-0.13,n≈40,m=0.We compared it with the corresponding hydrogen results and identified the importance of core effect for photoabsorption.
