Solid targets of Be, B, and C have been bombarded with 80-keV Ar/sup +/ ions, and photon emission from sputtered particles has been studied. For beryllium, several strong Be I and Be II emission lines have been observed, and the photon intensities have been converted to relative level population data. Essentially no radiation could be detected with a boron target, and only weak molecular emission was observed for carbon. The results are discussed. They are in accordance with the ideas behind a newly proposed electron-pickup model for atomic excitation in sputtering, but seem not to support a statistical (or binary-collision) model.
