Angular scattering effects in energy-gain spectra of A6+ (A=Ne,Ar,Kr,Xe) one-electron capture from He

Translational energy-gain spectra for single charge exchange in A6++He (A=Ne,Ar,Kr,Xe) collisions at 200-2000 eV energy have been recorded. It is found that in all systems at least two final channels are active. The experiments are compared with a simple semiclassical multistate collision model. The influence of angular scattering effects on energy-gain spectra is examined.
