The possibilities offered for activation analysis by using cyclotron-produced fast neutrons are investigated for the elements Mg, Al, Si, P, Zr, and Mo. Neutrons were produced by bombarding a thick beryllium target with 10- to 50-MeV deuterons. The use of a cyclotron in fast-neutron activation analysis has the advantages that rather high fast-neutron fluxes are available, and that, because of the variability of the neutron-energy spectra, optimum conditions with respect to sensitivity and interferences can be chosen. The experimental sensitivities obtained for Mg, Al, Si, P, and Zr range from 0.74 to 5.5 dpm/ng ..mu..A. These sensitivities are better by a factor of up to several hundred in comparison with data obtainable for 14-MeV neutrons. The extent of the interferences is, excluding some few exceptions, at about the same level for both techniques. 10 figures, 3 tables.
