Differential cross sections of the elementary process Ar/sup + +/(/sup 3/P)+He(/sup 1/S)..-->..Ar/sup +/(/sup 2/P)+He/sup +/(/sup 2/S) at collision energies between 0.6 and 1.6 eV were calculated using the quasiclassical treatment. Analytic potentials providing an approximation of the electronic energy of the system were employed to calculate deflection functions. Coupling of the diabatic terms was evaluated using the asymptotic method, and the Landau--Zener model was applied to account for the transition probability. Semiquantitative agreement of the calculated differential cross sections with those obtained in crossed beam experiments was achieved.
