摘要：

The electronic structure of Ag2O has been investigated by photoelectron, Auger-electron, and bremsstrahlung isochromat spectroscopy. The experimental results are compared with model one-particle band-structure and two-particle cluster calculations. We extract values for the on-site Ag 4d and O 2p energies, the Ag 4d O 2p transfer integrals, as well as the on-site Coulomb Ag 4d-4d and O 2p-2p interactions. A comparison with Cu2O and CuO is made, and the differences are discussed in view of high-Tc superconductivity and the instability of AgO. © 1990 The American Physical Society.
