Investigation on a high-Tc superconductor. La1.85Sr0.15CuO4, was performed in the wide range of Q-E space by means of neutron scattering and synchrotron radiation. The structure as well as the phonon dynamics showed a clear evolution at Tc. We found a spontaneous strain and phonon softening, which proves a strong coupling between lattice and superconductivity.
