摘要：

The temperature dependence of polarization-dependent EXAFS of a superconducting YBa2Cu3O7-delta thin film has been studied. The measurements were done on the Cu K-edge in the fluorescent mode over the temperature range 30-300K with the ab plane and the c axis parallel to the X-ray polarization vector, epsilon. The results indicate that the the values of mean square relative displacement sigma(2) of the nearest neighbor Cu-O pairs increase near Tc in the axial Cu-O bonds.
