Abstract

We report resonant inelastic x-ray measurements of insulating La₂CuO₄ and Sr₂CuO₂Cl₂ taken with the incident energy tuned near the Cu K absorption edge. We show that the spectra are well described in a shakeup picture in third-order perturbation theory which exhibits both incoming and outgoing resonances and demonstrate how to extract a spectral function from the raw data. We conclude by showing q-dependent measurements of the charge transfer gap.
