摘要
利用包括实散射的闭合轨道理论和分区自洽迭代的计算方法，研究了在标度能量ε^-=-0．03和标度电场f^-=0．01的情况下He（M=1）原子在平行电磁场中的闭合轨道和光吸收的回归谱．与相同条件下的He（M=0）原子的回归谱相比较，由于z轴处的排斥势，减小了原子实短程衍射效应和电子的关联，使谱变得简单，这与实验的结果一致．
We put forward a recurrence spectra of helium M = 1 atoms in a parallel electric and magnetic fields with a scaled energy ε^- = - 0.03 and constant scaled electric field at f^- = 0.01 in accordance with the closedorbit theory and spatial-splitting consistent method. The recurrence spectra of helium M = 1 atoms are compared with M= 0 in the same conditions. Because of the centrifugal barrier on z axis, the effects of diffraction of ionic core and the correlation of electrons are weakened. This makes the spectra considerably simple, which is completely consonant with the experiments.
