## Abstract

Exact quantum mechanical calculation of the reaction probability for the collinear H + H_{2} reaction on a Porter-Karplus potential energy surface are carried out by the finite-difference boundary value method at 6 energes in the threshold region and compared to close coupling, distorted wave, classical S matrix, transition state theory, and vibrational adiabatic calculations.
