A quantum scattering study of the collinear state-to-state reaction probabilities for the F+H-2(0)-> HF(upsilon ')+H system on a new potential energysurface

A new quantum scattering approach, linear combination of arrangement channe ls-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 re action probabilities for the F + H-2(0) --> HF(upsilon') + H system on the 6SEC potential energy surface (PES). The calculated results reflect the cha racter of PES accurately (there is a 'shallow hollow' along the reaction co ordinate on the 6SEC potential energy surface). They are compared with othe r theoretical research reported in the literature. It is shown that the LCA C-SW approach is one of the successful quantum scattering methods.
