Neutron diffraction topography with thermal neutrons has been used to observe the three‐dimensional strain fields in a hot‐pressed germanium crystal 8 mm thick. In the stereo‐paired and section topographs the strain fields were found to be columnar along the press direction. This result was confirmed by X‐ray diffraction topography performed on slices cut from the same crystal.
