Abstract
Elastic as well as charge transfer collisions of H++Xe have been investigated in a crossed beam experiment atE CM ≈30 and 50 eV. Opposite-phase oscillations have been observed in the elastic differential cross section with respect to the charge transfer differential cross section for the formation of Xe+(2 P 1/2). Taking advantage of the asymptotic quasi-degeneracy of the channels in question, this behavior has been qualitatively interpreted in terms of a simplified two-curve crossing model. The conditions of the validity of the model are discussed and its relation to the potential symmetry scattering in homonuclear systems is pointed out.
