摘要：

Copper 2P core level X-ray photoelectron spectra on several high T//c superconductors La//1//. //8//5Ba//0//. //1//5CuO//4, Y//1//. //2Ba//0//. //8CuO//4// minus // delta and Y//0//. //4B//0//. //6CuO//4// minus // delta oxides have been measured. The results indicate the coexistence of Cu**2** plus and Cu**3** plus these compounds.
