The inelastic scattering of neutrons by two‐magnon processes has been studied in MnF2at 4.2°K. The two‐magnon scattering was seen most clearly at the reciprocal lattice point (2&pgr;/a, 0, 0) where it took the form of a shoulder on the high‐frequency side of the one‐magnon peak with a well‐defined cut‐off in energy. Similar results were obtained at other wavevectors around this point but sharp peaks due to magnetovibrational scattering were then superposed on the broad two‐magnon scattering distribution. The line shape, the cut‐off in energy, and the intensity calculated from the cross‐section formulas are consistent with experiment.
