Time Dependent Wave Packet Study of the H<sup>-</sup>+ H<sub>2</sub> Nonreactive Scattering

Abstract

Time dependent wave packet calculations have been performed for the H − + H 2 nonreactive scattering, summed of elastic and inelastic probabilities, on the recent reported potential energy surface of the 3 H  systems. The total probabilities for total angular momentum J up to 35 have been calculated to get the converged integral cross sections over collision energy range of 0.20 -1.42 eV. Integral cross-sections and rate constants have been calculated from the wave packet transition probabilities for the initial states (υ = 0, j = 0) by means of J-shifting method and uniform J-shifting method for J > 0.
