Abstract: (arXiv)
We report results from a 2018 pilot run to study the feasibility of nuclear fragmentation measurements with the NA61/SHINE experiment at the CERN SPS. These results are important for the interpretation of the production of light secondary cosmic-ray nuclei (Li, Be, and B) in the Galaxy. The specific focus here is on cross sections important for the production of boron in the Galaxy from the interactions of 12^{12}C nuclei with hydrogen in the interstellar medium, including the contribution from the decay of the short-lived 11^{11}C fragments. The data were taken with the secondary 12^{12}C beam at beam momentum of 13.5 GeV/c per nucleon and two fixed targets, polyethylene (CH2_2) and graphite (C), from which we derive the cross sections of carbon on hydrogen. We present the measurement of the fragmentation cross sections of 11^{11}C, 11^{11}B, and 10^{10}B as well as the mass- and charge-changing cross sections.
