Measurement of Fragment Production Cross Sections in 1 GeV Proton Interactions with Carbon, Preprint

Double differential cross sections of fragment production in 1 GeV proton interactions with carbon were measured with a two-arm spectrometer installed at 30° and 126° with respect to the proton beam line of the PNIP synchrocyclotron. Mass and charge identifications of the fragments were performed by time-of-flight and Bragg spectroscopy methods for both registration angles. The obtained kinetic energy spectra were reproduced by moving source fits with a Maxelllian-like emission pattern.
