Cross sections for the reactions27Al(n, p)27Mg and28Si(n,p)28Al were measured by activation method between 13.40 and 14.83 MeV neutron energy. An accuracy of about 4% was achieved using the27Al(n, α)24Na reaction as a reference at 14.1 MeV where the relative excitation function has also been measured. Results obtained were compared to a recent compilation and that calculated by the Hauser-Feshbach model. Using the back-shifted level density formula and taking into account the contribution of the separated levels, the calculations were extended to the energy range from the threshold to 18 MeV. A structure was observed in the27Al(n, α)24Na reaction cross section curve around 14 MeV neutron energy.
