The vector correlations between products and reagents for the reaction Ca+CH3I→CaI+CH3 are studied using quasiclassical trajectory (QCT) method on extended London-Eyring-Polanyi-Sato potential energy surface (PES) at different collision energies. Four polarization dependent generalized differential cross-sections (2π/σ)(dσ00/dωt),(2π/σ)(dσ20/dωt),(2π/σ)(dσ22+/dωt) and (2π/σ)(dσ21-/dωt) have been presented in the center of mass frame, respectively. The distribution of dihedral angle,p(φr),the distribution of angle between k→ and j→,and the angular distribution of product rotational vectors in the forms of polar plots in and are calculated as well,the calculated results are in reasonably agreement with the experimental results.
