Stopping powers of 1.5-7.2 MeV 4He ions in Havar, nickel, Kapton and Mylar have been determined in transmission geometry. For Mylar, several foil thicknesses were used (3.7, 6.7, 12.1 μm) to check the foil thickness influence on the results. The stopping power values obtained were found to be independent of the foil thickness within the experimental accuracy of the present study (3%). The experimental values are compared with calculated values obtained by using Bragg's rule and the Ziegler semiempirical parameters. The available literature data is surveyed and compared with the values obtained in the present study.
