The excitation functions and absolute cross sections for the P/sup 31/ (n,p)Si/sup 31/ and Al/sup 27/(n, alpha )Na/sup 24/ reactions have bee n measured by the activation method for neutron energies below 9.5 Mev and at 14.1 Mev. The excitation function for P/sup 31/(n,p)Si/sup 31/ rises from 1.6 Mev to 5.5 Mev, is fairly constant at 0.14 barn to 9.5 Mev and considerably lower at 14 Mev. The Al/sup 27/(n, alpha )Na/sup 24/ excitation curve rises from 6 to 9 Mev neutron energy and is greater at 14 Mev. Comparisons are made with earlier measurements of the (auth)
