Stripping of high-energy krypton ions by various solid materials

Abstract
The charge-state distributions of 373-, 444-, and 552-MeV krypton ions passing through carbon foils of different thicknesses were measured; they were found to agree within about one charge state with the existing semiempirical predictions. Measurements of equilibrium distributions produced by Cu, Ag, and Au foils showed differences of two to three charge states when compared to C-foil results. Evidence is also given that the distributions are not significantly modified when the angle of observation is different from 0°.
