Abstract
We measure the Cu 2p X-ray photoemission spectrum (XPS) of Sr2CuO3 and analyze it by means of exact diagonalization calculations for (CunO3n)4n- clusters. In Sr2CuO3, the intensity ratio of the 3d9 satellite to the 3d10 L main line is 0.35–0.4, which is evidently smaller than that in the other high-T c related cuprates. We ascribe it as the smaller charge-transfer energy between the Cu 3d and O 2p. The origin of the broad main-line of Sr2CuO3 is also discussed.
