Stopping powers of solids for 16O ions at intermediate energies (20–95 MeV/u)

Abstract

The stopping powers of 11 solid media have been measured for 20–95 MeV/u oxygen ions from the french GANIL accelerator. The energy measurements were made using the LISE magnetic spectrometer. The accuracy in stopping power determinations is ± 1–2%. The data are in good agreement with semi-empirical values from Hubert et al. [Ann. Phys. (Paris) 5, supp. (1980)] and from Ziegler (Pergamon, New York, 1980) and with a scaling relative to the He 2+ ion stopping powers, assuming fully stripped ions inside the degrader.
