ملخص: The stopping powers of Al, Cu, Ag and Au solid targets for 32S and 79Br at E/A=2 MeV/u and for 127I at 1.47 MeV/u have been measured by the transmission technique using a high resolving power magnetic spectrometer and an associated position sensitive proportional gas counter as a detector system. The results are compared to the semi-empirical formula of Ziegler et al. and to the tabulation of Northcliffe and Schilling. Finally, they are used to set the limits of validity of the Hubert et al. formula at low incident energies.
