By investigating Hel spectral lines emitted by helium atoms after 30-50 keV HetHe collisions the post-collisional states of target and projectile atoms can be determined. Using in particular level-crossing and anticrossing spectroscopy we found that both target atoms resulting from direct excitation and projectile atoms resulting from capture excitation have extremely asymmetric charge distributions immediately after a collision. These results can be explained by the idea of Paul-trap promotion.
