SHAPE OF THE SPECTRAL LINE AND GAMMA ANGULAR DISTRIBUTION OF THE C-12(p,p 'gamma(4.44))C-12 REACTION

A model explaining the shape of the spectral line in the C-12(p,p'gamma(4.44))C-12 nuclear reaction has been applied to data collected during an experiment conducted at the Heidelberg Ion-Beam Therapy Center. Spectra were recorded for a graphite target setup, initial proton beam energies of 70.54 MeV and 88.97 MeV, which were later degraded before reaching the main target, and detection angles ranging from 90 degrees to 150 degrees. The model calculations reproduced experimental data and determined the angular distribution of the nuclear reaction. This article presents the details of the model along with a description of the subsequent analysis steps and results.
