Slowing down of 1.3–3.5 MeV/u Fe, Kr and I ions in ten metals

subject

description

Abstract Stopping powers for 1.3–3.5 MeV/u 56 Fe, 80, 84 Kr and 127 I ions in Mg, V, Fe, Co, Ni, Cu, Nb, Sn, Ta and Au have been determined by a transmission technique exposing the metallic sample foils to the direct ion beam. No previous data have been published for Mg, V, Fe, Co, Nb, Sn or Ta stopping media with these ion energies. The experimental results are compared with parametrizations of the stopping powers found in the literature (SRIM-2000 and Hubert’s parametrization). Discrepancies as high as 21 and 16% are observed for SRIM and Hubert’s parametrization, respectively. However, there is agreement between the present results and other experimental data available at corresponding ion velocities for 84 Kr and 56 Fe in Ni, Cu, and Au.
