The kernel of the distorted‐wave Born approximation ( DWBA ) transition amplitude will be explored with attention to the atom–diatomic molecule reactive scattering process of A + BC → AB + C . Our study of the kernel reveals valuable intrinsic properties regarding the state‐to‐state reactive scattering process. In particular, such a study will help us to better understand (i) the favored geometric configuration during collision, (ii) the spatial domain of contribution to the differential and total cross sections, and (iii) the structural dependence of the kernel distribution on the mass ratio of the reactant molecule BC and the departing atom C , particularly in the case of colinear rearrangement collisions. In this study we choose the FH 2 system as an illustration.
