Abstract: Differential cross sections of the reaction 7Li(p,p΄γ 1-0)7Li were experimentally determined in the proton energy range between 1000 and 4000 keV. The experiment was conducted at the Tandem Accelerator Laboratory of N.C.S.R. "Demokritos". The detection of the emitted gamma rays, having an energy E γ = 477.6 keV, was accomplished using four HPGe detectors of relative efficiency varying between 18 and 80%, at the detection angles of 0°, 55°, 90° and 165°. The statistical errors of the measurements did not exceed 4%, while the overall systematic uncertainty budget was also kept as low as possible (∼8%). For the validation of the obtained cross sections a benchmarking experiment was performed using a thick target of known stoichiometry. The comparison with existing experimental datasets in literature is also presented and discussed. [ABSTRACT FROM AUTHOR]
