Correlated fast ion stopping in magnetized classical plasma

Abstract

The results of a theoretical investigation on the stopping power of an ion pair in a magnetized electron plasma are presented, with particular emphasis on the two-ion correlation effects. The analysis is based on the assumptions that the magnetic field is classically strong ( λ B ⪡ a c ⪡ λ D , where λ B , a c and λ D are respectively the electron de Broglie wavelength, Larmor radius and Debye length) and that the velocity of the two ions is identical and fixed. The stopping power and vicinage function in a plasma are computed by retaining two-ion correlation effects and is compared with the results of the individual-projectile approximation.
