By means of small angle neutron scattering SANS using isotopic substitution the medium range structure of the amorphous Ni63Nb37-alloy was investigated. From the coherently scattered intensi­ty in the region of small momentum transfer the total and partial Bhatia-Thornton structure factors were determined. For (Q-values down to 0.03 Å-1 no small angle scattering effect at all was observed. Compared to amorphous Ni80P20 this means that apparently no small regions exits in amorphous Ni63Nb37. For 0.008 Å-1 ≤ Q ≤ 0.03 Å-1, corresponding to correlation lengths between 800 and 200 A, however. Scc and SNN increase with almost constant slope of about 3.6 in the log S(Q) - logQ presentation.
