Inelastic neutron scattering studies were performed on a powder and assembly of single crystals of La1.85Sr0.15CuO4. Phonon density of states and the Q-dependence of dynamic structure factor as well as the details of phonon scattering function were investigated as a function of temperature. We found specific phonon modes at the Brillouin zone center and the zone boundary showed an anomalous behavior.
