The measurement of isotopic cross sections of C-12 beam fragmentation on liquid hydrogen at 3.66 GeV/nucleon

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