Numerical Evaluation of Lindhard's Theory of Stopping Power for a Charged Particle in a Free-Electron Gas

Stopping powers derivable from Lindhard's dielectric theory of stopping for a charged particle in a uniform electron gas are calculated as a continuous function of electron density for a wide variety of projectile energies ranging from 10 (expn 2) to 10 (expn 4) keV/amu. Results are presented f...

Description
Summary:Stopping powers derivable from Lindhard's dielectric theory of stopping for a charged particle in a uniform electron gas are calculated as a continuous function of electron density for a wide variety of projectile energies ranging from 10 (expn 2) to 10 (expn 4) keV/amu. Results are presented for electron densities varying from 10 (expn 22) to 10 (expn 32) electrons/cc, a range which includes electron densities generally found for the energy bands of solids and for the atomic levels of atoms.
