利用多通道量子缺陷理论研究了HeH+的解离复合。我们研究了入射电子的部分波如何影响 DR 截面。 DR 截面取决于电子散射绝热 S 矩阵的部分波展开中心的位置。当里德伯态与氢原子的里德伯态在大核间距处相关时，中心应该在氢原子上，以便更好地收敛膨胀。
The dissociative recombination of HeH+is studied using multi-channel quantum defect theory. We investigated how the partial waves of incident electrons affect the DR cross section. The DR cross section depends on the position of the center of partial wave expansion for the adiabatic S-matrix of electron scattering. When the Rydberg states correlate with the Rydberg states of the hydrogen atom at large internuclear distances, the center should be on the hydrogen atom for a better convergence of the expansion.
