Abstract
From our systematic studies of the slowing down of Li-7, B-11, C-12, N -14 and O-16 ions in polymer films, Mylar (C10H8O4), polycarbonate (C1 6H14O3) and CR-39 nuclear track detector material (C12H18O7), the stop ping powers of solid hydrogen, carbon and oxygen have been extracted. The energies cover a range of 0.5-2.1 MeV/u. The validity of Bragg's a dditivity rule and the effects of the chemical state have been investi gated. The elemental stopping power data have been compared to semiemp irical model predictions. The model calculations show deviations from the experimental data, especially for Li-7 ions.
