Summary
The grazing angle scattering of fast heavy ions (He, Ne and Ar at 0.05 to 3.0 MeV) from copper and gold surfaces was investigated by measuring the angular distribution of the scattered ions distribution and observing the states of polarization of light emitted from excited states of the scattered ions. The ion distributions disagree significantly with those calculated by Firsov, but agree with previous lower velocity measurements. The polarization is strongly dependent on the angle of scattering, and evidence is shown that the atomic orientation depends principally upon the exit grazing angle. The surface collision mechanisms are discussed.
