Abstract
An experiment with 12C beam fragmentation on a liquid hydrogen target has been performed using the magnetic spectrometer, Anomalon, equipped with a Cherenkov charge detector, and the Dubna synchrophasotron at a projectile energy of 3.66 GeV/nucleon. A charge resolution of 0.26e (except for the hydrogen nuclei) and a mass resolution of 0.11-0.18 amu have been achieved. Isotopic and elemental fragmentation cross sections have been obtained for fragments from Z = 1 to 6. Decayed cross sections have also been calculated. We compare the measured cross sections with the results of other experiments and with calculations based on semi-empirical and parametric approaches.
