Abstract

High quality single crystals of Ba 1-x K x BiO 3 ( x =0; 0.15, 0.2, 0.33, 0.42) have been investigated by Raman light scattering in the 5-300 K temperature range. All spectra are interpreted as phonon states that are introduced in Raman scattering by folding back of modes from different points of the zone boundary due to structural distortions. Direct comparison of our spectra with inelastic neutron scattering data provides clear evidence for the existence of local R-type tilt and breathing distortions together with some additional distortion possibly related to the M-point.
