Abstract
The differential cross sections of the 2125keV γ-ray, emitted by the 11B(p,p′γ)11B reaction were measured at six (6) angles and at proton energies from 2.5 to 5.0MeV. The experimental setup consisted of three (3) 100% relative efficiency HPGe detectors placed on a motorized turntable. The comparison between the present measurements, which have an overall uncertainty of ∼8%, and previous ones from literature gives contradictory results. While there are large differences with previous differential cross-section measurements from literature, there is good agreement with previous thick-target yield ones. Additional thick-target measurements were performed in an effort to explain the observed discrepancies.
