摘要：
EELFS (Extended Energy Loss Fine Structure) measurements in the reflection mode have been performed at the O K edge of YBa2Cu3O7-delta thin films and sintered pellets in order to study the radial distribution function and its modification after the loss of oxygen induced by thermal heating. The Fourier analysis of the extended energy loss signal shows a O-Cu distance in the ceramic oxide slightly smaller than that in CuO.
