A new quantum scattering approach (linear combination of arrangement channels-scattering wavefunction, LCAC-SW) proposed by Deng and his co-workers is used to calculate collinear state-to-state reaction probabilities for the F+H~2(v=0)→HF(v')+H system on the 6SEC potential energy surface. The calculated results reflect the character of potential energy surface accurately (there is a "shallow hollow" along reaction coordinate on 6SEC potential energy surface). They are compared with other theoretical investigations reported in the literature. It is shown that the LCAC-SW approach is the successful one of quantum scattering methods.
