Correlated Fast Ion Stopping in Magnetized Classical Plasma

The results of a theoretical investigation on the stopping power of 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 ($\lambda_B\ll a_c\ll \lambda_D$, where $\lambda_B$, $a_c$ and $\lambda_D$ 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.
