Abstract
Stopping-power values and energy losses of 3.422.0-MeV Cn+12 ions were measured in the transmission geometry for 2.0-μm Havar, 2.8-μm nickel, 9.27-μm Kapton, and 3.8-μm and 6.9-μm Mylar foils. The experimental data were compared with calculated predictions obtained by using Bragg’s additivity rule and using the Andersen-Ziegler parameters for proton stopping with appropriate scaling for carbon ions. Furthermore, the data were compared with experimental values available in the literature. A distinct disagreement between the present results and calculated predictions was observed in the case of Havar and nickel.
