The energy loss of 6.1–16.9-MeV ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}_{}^{\mathrm{n}+}{}_{}{}^{}$ ions in 2.0-μm Havar, 2.8-μm nickel, 10.6-μm Kapton, and 6.5-μm aluminized (40-nm Al) Mylar foils has been determined. The measured energy losses are compared with the calculated values obtained by using Bragg’s rule and the Andersen and Ziegler parameters for proton stopping with appropriate scaling for heavy ions. The maximum deviations from the calculated values observed for Havar, nickel, and Kapton foils were 7%, 4%, and 3%, respectively. The experimental results agree with the calculations in the case of the Mylar foil, in the 6–10-MeV energy region for Havar, and in the 15–17-MeV energy region for nickel and Kapton foils.
