摘要：
EXAFS studies on CuBr of α, β and γ-phases are made on the basis of the anharmonic vibration model. It is found that the anharmonic vibrations are quite strong, even at 20 K, which is consistent with an investigation by means of infrared spectroscopy. Also obtained is a negative expansion of the Cu-Br distance at a temperature region higher than 300 K. © 1990.
