The magnetic form factors of iron and nickel have been studied by means of coherent inelastic vibrational scattering of polarized neutrons in high-symmetry directions for momentum transfers which are different from the reciprocal-lattice vectors. The vibrational scattering has been separated from other inelastic scattering processes, such as spin-wave scattering, by means of energy analysis on a triple-axis polarized-neutron spectrometer. In the case of iron we see definite departures from the interpolated elastic form factor, depending on the direction and magnitude of the scattering vector. In the case of nickel the inelastic form factor is identical, within experimental error, to the elastic form factor.
