Description
Summary:Differential elastic cross section have been measured for the scattering of O +( 4S) on Ar over an energy range of E lab = 2–20 eV: An inversion procedure has been applied for the evaluation of the potential; information about the relative heights of the cross section have been used to determine the equilibrium distance. Reduced variables allow the generation of one single phase function using cross sections obtained at different energies. The potential parameters have been found to be r m = 2.02 ± 0.08 Å and D e = 0.68 ± 0.02 eV, the potential symmetry being 4Σ −; distortion by potential branches of excited states could be ruled out.
