• Quasi-monoenergetic neutron
• neutron energies of 15.2 similar to 37.2 MeV
• activation technique
• off-line gamma-ray spectrometry
• Al-27(n,alpha)Na-24 and Al-27(n,p)Mg-27 reactions
• cross section

The cross sections of the Al-27(n,alpha)Na-24 and Al-27(n,p)Mg-27 reactions with the average neutron energies of 15.2, 26.4, and 37.2 MeV were measured using the activation and off-line gamma-ray spectrometric technique at the Korean Institute of Radiological and Medical Sciences (KIRAMS), Korea. Quasi-monoenergetic neutrons produced via the Be-9(p,n) reaction with the proton beam energies of 25, 35, and 45 MeV from the MC50 cyclotron of KIRAMS were used. The present measured values were compared with those from the evaluated nuclear data libraries ENDF/B-VII, TENDL-2015, TALYS 1.8, and from literature. In general, a close agreement with the literature data as well as the evaluated data was found.
