ZERO-ENERGY DENSITY EFFECT IN STOPPING POWER OF CARBON.

Zero-energy density effect in stopping power of carbon has been studied. A modified Drude dielectric function was used to describe the interaction of incident electrons with the valence band of graphite, glassy carbon and diamond. The Hartree-Fock generalized oscillator strength was employed to evaluate the stopping power of gaseous carbon. Results were analyzed with respect to density, structure and phase.
