Energy-dependent charge-changing cross sections and proton distribution of 28Si

• The charge-changing cross sections (σcc) of 28Si on a carbon target were measured with high precision atintermediate energies from 100 to 600 MeV/nucleon. The measured σcc decreases rapidly from low energies upto 200 MeV/nucleon, whereas at higher energies it appears almost constant. The energy dependence of σcc iscompared with a Glauber-type model calculation where only the proton distribution of 28Si is taken into account.A phenomenological correction factor deduced from the present data satisfactorily reproduces the experimentalσcc for other stable nuclei, whose charge distributions were determined by electron scattering and muon captureexperiments.
