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 102 to 104 keV/amu. Results are presented for electron densities varying from 1022 to 1032 electrons/cm3, a range which includes electron densities generally found for the energy bands of solids and for the atomic levels of atoms.
