Abstract
Inelastic scattering measurements have revealed an anomalous behaviour of a TA-branch, which is related to structural distortions along K+-chains. Additional weak diffuse intensity shows similarities with a Peierls distortion. A quasielastic component vanishing at higher temperatures reflects the response of the framework of the diffusive K-motions.
