The nucleation stages of the decomposition reaction in a {sup 58}Ni-13at%Al alloy at T = 450 C have been investigated by means of small- and wide-angle polarized neutron scattering. The use of the {sup 58}Ni isotope for the sample preparation tremendously reduced the incoherent scattering of the matrix. This, together with the application of polarized neutrons for experiments at T = 12 K, made the detection of extremely small Ni{sub 3}Al clusters, not accessible to other microanalytical tools, with diameters D < 1 nm feasible.
