Phys. Rev. Lett. 80, 2469–2472 (1998)Mechanism of Electron Emission from Al(100) Bombarded by Slow Li+ IonsReceived 19 September 1997; published in the issue dated 16 March 1998 Emission of electrons from Al(100) during bombardment by 50–520 eV Li+ ions was measured as a function of incident ion energy and direction. The process was modeled by a surface electron-hole pair excitation mechanism and was quantified with a one-electron parametric theory. This is a previously unidentified mechanism which is characterized by a strong dependence on the energy and angle of incidence of the primary particle. Good agreement between the experimental data and theory is found, which indicates that this mechanism is indeed responsible for electron emission during Li-Ai collisions. © 1998 The American Physical Society URL:
