Abstract

The critical scattering near the phase transition of RbCaF3 from its cubic O1h(Pm3m) to the tetragonal D184h(14/mcm) structure at Tc = 196 K is investigated. Mössbauer diffraction is applied to separate elastic and inelastic scattering intensities with energy resolution of 60 neV. The influence of domains is shown from X-ray diffraction
