Abstract
The angles of tilt of the anion octahedra in NaNbO3 have been calculated from measurements of the intensities of very weak x-ray difference reflections. Their variation with temperature is shown and compared with values calculated directly from lattice parameter measurements. The Nb displacements have also been calculated from the intensities of difference reflections.Keywords
