摘要：
The phonon density of states (PDOS) is determined by inelastic neutron spectroscopy for a series of HTC compounds as (Y, Ca) (Ba. La) Cu3O7-delta and (La, Sr) CuO4. A general results is the occurrence of typical shifts for high energy Cu-O bond stretching modes which support the assumption of a strong electron-phonon coupling in these materials.
