Stopping Power of Charged Particles I

The stopping power and the stopping number, respectively, of charged particles are determined in the frame of the dielectric formalism in random phase approximation. The high and low velocity limits are disscussed. Numerical evalution is given for arbitrary masses of the projectile particle using a dielectric function ϵ(κ, ω) valid for all values of degeneracy. The connection with transport (e.g. electrical resistivity) is considered.
