Abstract
Recently discovered layered-perovskite superconductor Sr2RuO4 shows si gnificant spectral weight redistribution in its low energy photoemissi on spectrum. This suggests the existence of strong electron correlatio n in the system. Renormalized mass is estimated by the phenomenoiogica l analysis of the spectrum. The importance of a momentum-dependent par t of the self-energy is discussed.
