Abstract
H+H2 collisions at higher impact parameters can result in the trajectory being deflected towards a collinear H3 configuration by the long range barrier to the insertion mechanism. When the H2 molecule is stretched, this trajectory will be temporarily trapped within a well about the collinear configuration. Samples of 3-D classical trajectories computed on the SLTH potential provide examples of collisions with long delay times which result from this trapping. The higher-b mechanism may be responsible for the resonances seen in the Nieh and Valentini experiment. If so, these resonances are primarily sensitive to the details of the H3 potential at longer range ({A figure is presented} au) for a stretched H2 molecule ({A figure is presented} au) and sideways approach.
