摘要：

Pulsed neutron scattering studies carried out with the atomic pair distribution method show that the actual atomic structure of superconducting oxides has significant local deviation from the crystallographic average structure, and the deviation shows an anomalous change through the superconducting transition. This anomaly is likely to provide information regarding the coupling mechanism.
