Abstract

The results of a polarized light scattering study of single-crystal YBa2Cu3O7-δ are presented. Strong interband electronic scattering in YBa2Cu3O7-δ is observed through interference effects with certain phonons. Below Tc, this electronic scattering undergoes a redistribution due to gap formation, which is monitored by a rapid change in the damping rates of the strongly coupled phonons. Our lowest temperature data further indicates the presence of residual electronic scattering well below the expected 2Δ gap onset, suggesting that a continuum of electronic states exists inside the gap.
