Measurement of the stopping power for 16O in 4He gas

The stopping power for 16O ions in 4He gas from 1 to 31 MeV is measured using an indirect method. The 16O beam of fixed energy entered a scattering chamber filled with 4He gas at different pressures and its residual energy is measured. The stopping power is determined by differentiating the thickness versus residual energy curve. The measured stopping power is compared with those calculated with the codes SRIM and MSTAR.
