### Abstract:

Abstract The differential cross sections of the 2125 keV $\gamma$–ray, emitted by the $^{11}$B(p, p'$\gamma$)$^{11}$B reaction were measured at six (6) angles and at proton energies from 2.5 to 5.0 MeV. 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 $\sim$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.
