✦ Synopsis

A tight-binding model is used to calculate the low energy Raman continua of YBa2Cu3Oy assuming the existence of an anisotropic gap with d-wave symmetry. Good agreement with the measured spectra is obtained for Alg symmetry but the relative intensities and peak positions of the Blg and B2g spectra are not well reproduced by the model.
