Low ion velocity slowing down in a strongly magnetized plasma target

Ion projectile stopping at velocity smaller than target electron thermal velocity in a strong magnetic field, is investigated within a novel diffusion formulation (Dufty-Berkovsky), based on Green-Kubo integrands evaluated in magnetized one component plasma models, respectively framed on target ions and electrons. Analytic expressions are reported for slowing down orthogonal and parallel to an arbitrary large magnetic field, which are free from the usual uncertainties plaguing the standard perturbative derivations.
