Abstract: (APS)
Measurements of the ionization losses of 10.0- to 30-keV Ge72* atoms in germanium show no evidence for a cutoff for particle energies less than 23 keV, as might be expected from adiabatic arguments concerning the effect of an energy gap in germanium. The ionization loss is consistent with Lindhard's conjecture that the electronic stopping power of heavy particles is proportional to the particle velocity even at energies far less than this cutoff energy. Any effective energy gap encountered by the germanium atoms moving in a germanium crystal is less than ∼0.1-0.2 eV.References(9)
