Local Structural Anomaly at Tc Observed by Neutron Scattering
One would expect that the onset of superconductivity might leave a signature on the atomic structure of the high temperature superconducting oxides, if the electron-lattice interaction is strong and totally or partially accounts for the occurance of superconductivity. For this reason the structural change at Tc has been the subject of considerable interest.
