摘要
A study has been made of photon-emission induced by impact of H** plus and He** plus ions on gold and nickel metallic surfaces. An energy selected beam is directed onto a metal surface and the emitted light is analyzed by a monochromator. No singlet lines of helium were observed and also no line emissions from the target material. The line-shape of the He-lines has been studied in detail. The shape can be qualitatively explained by Doppler shifts of emission from projectiles scattered by bi-particle collisons in the surface. The total intensity of the lines increases as a function of beam energy and of incidence angle on the surface.
