我们已经通过 75 keV 质子撞击进行了 H2 电离的运动学完整实验。将测量中提取的三重微分截面 (TDCS) 与三种不同电子喷射几何形状的分子三体扭曲波 (M3DW) 计算进行比较。总体而言，对于同一射弹，实验与理论之间的一致性比氦靶的情况更好。然而，仍然存在显着的定量差异，这可能是由捕获通道造成的，捕获通道可能与电离通道强烈耦合。因此，非扰动耦合通道方法有望改善一致性。
We have performed a kinematically complete experiment on ionization of H2 by 75 keV proton impact. The triple differential cross sections (TDCS) extracted from the measurement were compared to a molecular 3-body distorted wave (M3DW) calculation for three different electron ejection geometries. Overall, the agreement between experiment and theory is better than in the case of a helium target for the same projectile. Nevertheless, significant quantitative discrepancies remain, which probably result from the capture channel, which may be strongly coupled to the ionization channel. Therefore, improved agreement could be expected from a non-perturbative coupled-channel approach.
