A quantum scattering study of collinear reaction probabilities for the fluorine atom and hydrogen molecule system

A new quantum scattering approach (linear combination of arrangement channe ls - scattering wavefunction, LCAC - SW) proposed by Deng and his co - work ers is used to calculate collinear state to - state reaction probabilities for the F + H-2(upsilon = 0)-->HF(v') + II system on the 6SEC potential ene rgy surface. The calculated results reflect the character of potential ener gy surface accurately (there is a "shallow hollow" along reaction coordinat e on 6SEC potential energy surface), They are compared with other theoretic al investigations reported in the literature, It is shown that the LCAC - S W approach is the successful one of quantum scattering methods.
