"Kinetic electron emission induced by grazing scattering of slow atoms: Local probe of the Compton profile near the fermi edge";
Physical Review B,
Kinetic electron emission induced by noble gas atoms impinging at low keV energies on an Al 111 surface
under a grazing angle of incidence is studied by coincident time-of-flight and electron number spectroscopy.
We observe small but defined yields for electron emission at impact velocities below the "classical" threshold
for kinetic emission of quasifree metal electrons. An analysis within the impulse approximation indicates that
subthreshold emission may serve as a probe for the local electron momentum distribution Compton profile
above the topmost layer of metal targets.
