Sr2CuO2Cl2. Represents an almost excellent scenario of the two-D antiferromagnetic CuO2-aircraft and thus is of specific interest during the context with the origins of substantial TC superconductivity. We have now calculated experimentally and analyzed theoretically the Ti 2p X-ray photoemission spectra (XPS) along with the resonant enhancement of valence photoemissionat https://okada4dsg.com/
