Kurzfassung englisch:
Kinetic electron emission induced by grazing scattering of low energy (keV) H and noble gas
(He, Ne, Ar) ground state atoms on monocrystalline flat metal surfaces has been studied by
coincident measurements of the projectile time-of-flight and the number of ejected electrons.
This technique permits precise measurements of unprecedently small KE yields (< 10-4
electrons per projectile) [1]. We have focused on kinetic electron emission (KE) near and
below the "classical" KE threshold which corresponds to the minimum momentum transfer
from projectiles to quasi-free metal electrons for excitation of these electrons from the Fermi
edge into vacuum [2,3].
