Sr2CuO2Cl2. represents a nearly great scenario of the two-D antiferromagnetic CuO2-aircraft and therefore is of individual desire while in the context on the origins of superior TC superconductivity. Now we have calculated experimentally and analyzed theoretically the Ti 2p X-ray photoemission spectra (XPS) plus the resonant enhancement of valence photoemissionat https://okada4dsg.com/
