Abstract
Collisions of 200-600 keV ions of He, Ne, and Ar with aluminium surfaces have been found to result in the emission of intense continua in the vacuum-UV region. Continua extend from 680 to 990 AA for He, 700-950 AA for Ne and 1095-1425 AA for Ar. The origin of the continuous emission has been interpreted as due to the interaction of accumulated gas atoms in the discrete excited state with identical atoms in their ground state. The spectra result as a consequence of Franck-Condon transitions in the diatomic collision complex.Keywords
