摘要：

We report inelastic neutron scattering measurements of the generalized phonon density of states in superconducting Pr2-xCexCuO4 and insulating Pr2CuO4. Substantial decreases in the peak intensities of some of the phonon features, and an increase in the intensity of one of the peaks, were observed as the material is changed from the insulating parent compound to the superconductor. The results suggest that phonons are involved in the formation of the superconducting state in these electron-superconductor materials.
