Abstract

We report γ-ray spectra for the line observed at Eγ = 4.44 MeV in our previous experiments at iThemba LABS' SSC facility using 30-200 MeV proton beams to irradiate a natC target. It is actually a complex composed of several lines of interest broadened by Doppler effect. In addition to the dominant 4.439 MeV line of 12C, two other lines at Eγ = 4.319 and 4.445 MeV assigned to 11C and 11B, respectively, are significant components of this complex. The analysis of its line shapes based on nuclear reaction models is the main topic of this contribution.
