COMPUTATIONAL STUDY OF THE EFFECT OF THE INTERACTION POTENTIAL FOR INELASTIC ATOM-MOLECULE ROTATIONAL SCATTERING

Approximate coupled channel scattering calculations are performed for model systems comprising a closed-shell atom colliding with rigid rotor diatomic homo- and hetero-nuclear molecules. Differential and total cross-sections for rotational scattering with several different interaction potentials are given for p-H2 and MuH + He, at a fixed total collision energy, and for LiF + Ar with a fixed emperical potential but varying collision energy. Conclusions are drawn concerning the effect on the cross-sections of the variations made. © 1979.
