The influence of uniaxial mechanical pressure σm ≤ 150 bar on the spectral (300–800 nm) dependence of the birefringence Δni of (NH4)2SO4 crystals is studied. The dispersion Δni(λ) is shown to be normal and greatly increases when approaching t

The unit-cell parameters and the spatial symmetry of RbKSO4 crystals are determined. The temperature and spectral dependences of the refractive indices and birefringence of these crystals are measured. Two first-order phase transitions are found to o
