Low Velocity Ion Stopping in Binary Ionic Mixtures

We investigate the basic features underlying the low ion velocity (Vp) slowing down (LIVSD) in multicomponent and dense target plasmas built of quasi-classical electron fluids neutralizing binary ionic mixtures (BIM)such as deuterium-tritium of current fusion interest,proton-heliumlike iron in the solar interior or proton-helium ions considered in planetology, as well as other mixtures of fiducial concern in the heavy ion beam production of warm dense matter (WDM) at Bragg peak conditions [1]. The target plasma is taken in a multicomponent dielectric Fried-Conte formulation. We also focus attention on so-called critical Vp values featuring same LIVSD on target ions and electrons,respectively. BIM including negative hydrogen are also given attention [2].\\[4pt] [1] B.
