• Ammonium sulfate was studied by X-ray diffraction. The integrated intensitiesfor some of the Bragg reflections decreased discontinuously at the transition tem-perature -50'C as the temperature was decreased. The fact cannot be explainedby the typical order-disorder model. X-ray diffuse scattering was studied at roomtemperature and -47'C. It was observed that the intensities of diffuse streaksalong the [100] direction in the reciprocal space were markedly enhanced as thespecinten was cooled. The diffuse scattering was analysed by the soft mode naodeland the observed intensit>r distribtution was exr>Iained c?ualitativel>' b>' the asstunaedsoftening of the libration of sulfate ions which satisfy the B.. synvmetry. Thepossibility of the analysis of the diffuse scattering by the order-disorder modelwas also discussed.
