摘要：

We have used inelastic neutron scattering techniques to measure the dispersion of the singlet-doublet magnetic excitons of the Pr3+ ions in the singlet ground state system Pr2CuO4. The excitons exhibit significant dispersion both within the basal plane as well as along the c-axis direction, directly demonstrating the Pr-Pr exchange interactions. These exchange interactions must be mediated through the CuO2 layers involved in the formation of the superconducting state.
