Abstract

Total differential cross section (DCS) measurements in the thermal energy range have been carried out for Ne-O2, Ne-NO, Ar-O2, Ar-N2, He-Cl2, Ne-Cl2, and Ar-Cl2 under high-resolution conditions, which Fiave always permitted to resolve the diffraction and/or rainbow oscillations. Reliable full anisotropic potential energy surfaces have been derived by also simultaneously fitting all other available experimental properties in a multiproperty fashion within the framework of the infinite-order-sudden approximation, which has been shown to be accurate under the present experimental conditions. Information on the anisotropy of the interaction is obtained from the quenching of the diffraction and rainbow structure in the total DCS.
