Abstract

The differential cross sections for the H2(p,pp)n reaction have been measured for 84 angular configurations of the outgoing protons in the range of polar angles from 13° to 33° with a proton beam of 108 MeV. Data have been collected in the Cyclotron Center Bronowice at the Institute of Nuclear Physics PAS in Kracow using the BINA detector setup. Analysis leading to determination of the breakup cross-section values is described. Absolute normalization is obtained by normalization to the simultaneously measured H2(p,d)p scattering events. Experimental results are compared to the state-of-the-art theoretical calculations. Global analysis shows significant influence of the Coulomb interaction and small effects of three-nucleon force in the studied phase-space region.
