Reactive scattering for different isotopologues of the H3(-) system: comparison of different potential energy surfaces.

Reaction probabilities and cross sections for the ion-neutral molecule collision H(-) + H2 and its different isotopologues are presented. Quasi-classical trajectory, time-independent, and time-dependent quantum calculations are compared with experimental results. In the calculations, three different ab initio potentials have been used to clarify their applicability.
