Light emitted by Na atoms following the bombardment of a NaCl target with 48 keV Ar ions has been studied. Results for light yields which have been obtained as a function of incident Ar ion beam charge state are reported that include contributions from both displaced surface and sputtered atoms. Secondary electron yields from a NaCl target have also been obtained as a function of Ar ion charge state. The electron spectra show clear evidence for the emission of Cl Auger electrons, independent of the Ar ion charge state. The overall yield of electrons is found to change substantially with charge state. Correlations between the light emission and electron emission are considered. © 1995.
