Abstract We have separated the sputtering patterns of NaCl irradiated with low energy electrons into component features from the directional ejection of halogen atoms and a random evaporation of the metal atoms. The sputtering yields anti-correlate with exciton luminescence. Lifetime studies reveal the presence of several exciton states with different diffusion energies. The sputtering yield shows a resonance with the production of surface excitons. The experiments confirm the view that defect formation in the halogen sub-lattice proceeds by a non-radiative exciton decay which initiates a replacement collision sequence along a chain of halogen ions.
