Low ion velocity slowing down in a strongly magnetized plasma target

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