Numerical Calculations for the Reaction Probabilities of the Collinear H+H₂ (0) Reaction with LCAC-SW Method

The reaction probabilities of the collinear H+H₂（0） →H₂+H reaction are calculated with LCAC-SW method.The results we’ve obtaned agree well with the EQ values,even using small base sets （the number of vibrational base functions n_tib=10,the number of distributed Gauss functions n_gas=10）.The calculated threshold energy for the colliear H+H₂ （0） reaction is about at E=0.45eV and the reaction probabilities P^R₀₀ for the ground state to ground state has a shap resonance peak at E=1.27eV.
