Abstract
The generalized phonon density of states (GDOS) is obtained from the measuring data and compared to model calculations. By means of the partial densities of states which are obtained from these calculations observed structures in the GDOS can be attributed to particular vibrations of atoms. Most significant are shifts of high frequency oxygen modes which are observed upon cooling. These findings seem to be connected with the transition into the superconducting state.
