Polarized resonance photoemission forNd2CuO4

We present calculations of resonance photoemission spectra for ${\mathrm{Nd}}_2$ ${\mathrm{CuO}}_4$. The calculations use a model Hamiltonian for which all parameters for the valence electrons are obtained from ab initio calculations or atomic data. Most features of the calculated sp agree well with experiment where comparison is possible. A substantial dependence on the polarization of the light is predicted for the occurrence of resonance behavior, and for the off-resonance intensity of the local singlet and one of the satellites.
