We have focused attention on several experimental and theoretical results on the study of the collisional detachment of H~ and have shown that the electron energy spectra at and near O° contains information on the dynamics of the detachment process. In particular, we drew attention to the fact that the low energy continuum states of H~ are undistorted by the rapidly receding target and that, because of this, the manifold of low energy three-particle continuum states seems to be an especially rich source of information on the dynamics of the three-body Coulomb problem. The experimental advantage provided by the fast moving H~ beam serves to make an interesting connection between fast atomic collisions and low energy final states.
