Abstract

We report particle-hole excitations in a cuprate insulator in the intermediate regimes of momentum-transfers (qao to approximately 1.4 π-3.1 π, where q is the scattering vector and ao is the lattice constant) using high energy inelastic X-ray scattering. The excitation spectra show dispersive features near the Mott edge which shed light on the momentum structure of the upper Hubbard band in cuprates. We discuss the potential use of such a technique to study the momentum dependence of unoccupied bands in complex insulators.
