Abstract

The large-cluster effect on the Cu 2p X-ray photoemission spectrum (XPS) for quasi-one-dimensional Cu-O systems, such as Sr₂CuO₃, CuGeO₃ and LiCuO₂, is discussed. Recent experiments clearly show that the line shape of the main peak (d¹⁰L(Combining low line)) differs for these systems, although it must be a structureless narrow peak for all of them within the framework of a CuO₄ cluster model analysis. It is shown that whether the Cu-O-Cu bond angle is 90° or 180° is a key factor in discussing the Cu 2p main-line shape as well as the magnetic coupling between the Cu spins.
