A quantum scattering study of the collinear state-to-state reaction probabilities for the F+H2(0)→HF(υ′)+H system on a new potential energy surface

A new quantum scattering approach, linear combination of arrangement channels-scattering wavefunction (LCAC-SW) proposed by Deng and co-workers [Sci. China B 24 (1994) 463] is used to calculate the collinear state-to-state reaction probabilities for the F + H-2(0) --> HF(upsilon') + H system on the 6SEC potential energy surface (PES). The calculated results reflect the character of PES accurately (there is a 'shallow hollow' along the reaction coordinate on the 6SEC potential energy surface). They are compared with other theoretical research reported in the literature. It is shown that the LCAC-SW approach is one of the successful quantum scattering methods. (C) 1999 Elsevier Science B.V.
