"Electron emission and energy loss in grazing collisions of protons with insulator surfaces";
Physical Review A,
Electron emission from LiF, KCl, and KI crystal surfaces during grazing collisions of swift protons is
studied using a first-order distorted-wave formalism. Owing to the localized character of the electronic structure
of these surfaces, we propose a model that allows us to describe the process as a sequence of atomic
transitions from different target ions. Experimental results are presented for electron emission from LiF and KI
and energy loss from KI surfaces. Calculations show reasonable agreement with these experimental data. The
role played by the charge of the incident particle is also investigated.
