Activation method was employed to measure the cross section for the 58 Ni(n,pα) 54 Mn and 63 Cu(n,pα) 59 Fe reactions in the energy range from the threshold up to 21 MeV. The quasi-monoenergetic neutrons in the energy range from 14 to 21 MeV were produced via the 3 H(d,n) 4 He reaction at 1, 2, 3 and 4 MeV incident deuteron energies. High purity Ni and Cu samples with natural isotopic composition and dimensions of ϕ12x5 mm and ϕ20x5 mm respectively were utilized. The gamma-ray spectrometry using HPGe detector was utilized to measure the activity induced in the sample. The cross sections were determined relative to the standard cross section the 27 Al(n,α) 24 Na reaction. The results for the 63 Cu(n,pα) 59 Fe reaction cross section were obtained for the first time.
