The electron momentum density of the unconventional superconductor Sr2RuO4 has been studied using the high-resolution Compton scattering technique. Compton profiles have been measured along the [100], [110], and [210] directions, and compared with theoretical profiles calculated using the full potential linearized augmented plane wave method within the local density approximation. The calculated and measured electron momentum distributions, as obtained by the Compton profiles, are in good agreement with respect to their overall shapes and anisotropies in the Compton profiles. Theoretical analyses have shown that the amplitude of the anisotropies is dominated by the filled bands which possess Ru 4d and O 2p bonding characters in the RuO2 planes.
