Abstract
The temperature dependence of order parameters such as spontaneous strains and atomic displacements in benzil (C6H5COCOC6H5) has been obtained by the x‐ray diffraction method. The diffuse x‐ray scattering has also been examined just above the transition temperature (Tc = 83.5 K). It has been found that the primary order parameter is a spontaneous strain ezx and the benzil crystal is ferroelastic below Tc.Keywords
