State-to-state reaction probabilities for H- + Hz, D2 collisions

The potential energy surfaces for the ground and low-lying excited states of the H; system are calculated by means of the diatomics-in-molecule (DIM) method. State-to-state reaction probabilities for rearrangement in H-+HZ, D, collisions are cal-culated by the S matrix Kohn variational method in the discrete variable representation for the collinear configuration, and the results for H- + D, collisions compared with recent experimental data. 1
