Differential cross section measurements of the 9Be(3He,p)11B reaction for NRA applications

The differential cross sections of the 9Be(3He, )11B reactions for i = 0–6 were determined within the laboratory energy range 1.24–2.87 MeV and for backward angles from 107 to 164 with 2 steps using two double sided silicon strip detectors. The obtained cross sections covered the angle and energy ranges typically used for the analysis of beryllium targets with the nuclear reaction analysis technique. The experiments were carried out at the Ruđer Bošković Institute and the determined cross sections were benchmarked with the measurement of thick target reaction yields from a pure beryllium target at two beam energies, 1.8 and 2.7 MeV. The results are presented in graphical form and for 134 and 164 are also given as tables in the Appendix. The correctness of the data, verified through the comparison of thick target spectra as well as the observed discrepancies with previous data are discussed and analyzed.
