摘　　要：利用半经典闭合轨道理论和分区自洽迭代方法计算了Rydberg态下He2+在平行电磁场中的回归谱与闭合轨道.为了模拟分子实的散射作用,引入一个包含电子交换势的新势能.利用这一新势能,结合多通道量子亏损和分子闭合轨道理论,讨论了分子实散射效应对平行电磁场中He2+的回归谱与闭合轨道的影响.By the semi-classical closed orbit theory and region-splitting consistent iteration method, we calculated the recurrence spectra and closed orbits of He2^＋ in parallel electric and magnetic fields. Using the new potential with electronic exchange interaction, complex channel quantum defects and molecular closed orbits theory, we discussed the influence of molecular core to the recurrence spectra and closed orbits.
