Precise Measurement Of The Integral Cross-Section For The Reaction Mg-24(N,P)Na-24 Between 13.5 And 18.0 Mev

Activation technique has been used to measure the cross-section ratio for 24Mg(n,p)24Na and 27Al(n,a)24Na reactions, the last being a reference one. The reaction T(d,n)4 He was used to produce the neutrons. Countings of γ-spectra were performed with a 75 × 75-mm NaI (T1) detector. The new cross-section values for 24Mg were calculated based on the best values of the 27Al-reaction cross-sections for respective neutron energies. In general, the obtained total error is 1.5–2 times smaller than previously.
