Anomalous low-temperature behaviour of is observed by both Raman-spectroscopy using laser excitation Cu 2 O frequencies near the resonance of the 1S "blue excitonΓ and x-ray powder di β ractometry using a high-resolution Guinier Γlm camera. Changes in frequency of the Raman-allowed phonon band, and a
