Abstract
The differential screened Rutherford-scattering cross sections of 2-15 MeV Cl, 2 and 4 MeV Br, and 5 and 15 MeV Au ions on Au atoms have been measured, utilising a transmission-scattering geometry and targets consisting of very thin (2-10 AA) layers of gold evaporated onto 150-270 AA thick carbon foils. The measured cross sections are not influenced by multiple scattering, and a careful examination of the target composition during irradiation has been performed. In outline, the measurements confirm the scaling properties inherent in the theory of Lindhard et al. (1968). Some deviations from the t1/2 scaling as well as from the actual size of the Thomas-Fermi cross section are, however, observed at t1/2 values smaller than three.Keywords
