Raman scattering in YBa2Cu3O7-δ (theory)
Rashba E. I., Sherman E. Ya.
The Raman scattering spectra of YBa2Cu307 _ δ are analyzed at a qualitative level. Arguments are presented to support the suggestion that bridges connecting planes and chains play a definite role in the formation of the predominant polarization of the oxygen A bands along the с axis.
