· Phys. Rev. B: Condens. Matter; (United States)
Results of Raman scattering studies on the natural isotope superconductor YBa/sub 2/Cu/sub 3/O/sub 7-//sub x/ and the heavy isotope superconductor YBa/sub 2//sup 65/Cu/sub 3/O/sub 7-//sub x/ are presented. The phonon at 148.6 cm/sup -1/ down-shifted by 1.8 cm/sup -1/ in YBa/sub 2//sup 65/Cu/sub 3/O/sub 7-//sub x/ whereas the position of the phonon at 112.5 cm/sup -1/ remains unchanged. This conclusively relates the phonon mode at 148.6 cm/sup -1/ to the vibration of Cu(2) atoms and suggests that the phonon at 112.5 cm/sup -1/ is independent of Cu vibrations.
