Four mathematical dimensional quantum mechanical studies of tetra-atom systems: State-to-state J=0 probabilities for the H-2+OH->H2O+H reaction

This paper presents reactive state-to-state J=0 probabilities for the title system as obtained in a four-mathematical-dimensional quantum mechanical treatment. The present treatment differs from our previous one by the fact that in addition to the three Jacobi radial coordinates also the angular coordinate related to the H-2 axis is treated as coordinates. As a result only the Jacobi angle related to the OH axis is treated as a parameter and the final probabilities follow from an integration over this angle (the out-of-plane angle, beta, is eliminated by using a beta-averaged potential). The calculations yielded final rotational and vibrational distributions that were analyzed and discussed with respect to more accurate (i.e., five-and six-mathematical-dimensional) results.
