摘要：

The Cu L(alpha) and O K(alpha) X-ray emission spectra of YBa2Cu4Og have been measured. Compared to YBa2Cu3O6.9, a distinct high-binding energy feature appears in the O K(alpha) spectrum and the O 2p states shift slightly from the Fermi level, while the binding energy of Cu 3d states does not change. The role of the apical and chain oxygen is discussed.
