Angular studies of potential electron emission in the interaction of slow ions with Al surfaces
Riccardi P; Barone P; Bonanno A; Oliva A; Baragiola RA.
Phys Rev Lett ; 84(2): 378-81, 2000 Jan 10.

ABSTRACT

We report energy distributions of electrons emitted from Al surfaces under impact by 1 keV Ar+ and 1-5 keV Ne+ ions. The variation of the energy distributions with the angle of incidence is different for both ions and provides information on the mechanism responsible for electron emission. For Ar+ electron emission results mainly from Auger neutralization, while for Ne+ an important emission mechanism is the decay of plasmon excitations. We find a transition between surface and bulk plasmon excitations as the energy of the ion is increased.
