Sr2CuO2Cl2. Represents an almost great scenario of a 2-D antiferromagnetic CuO2-airplane and therefore is of unique desire during the context of the origins of superior TC superconductivity. We have now measured experimentally and analyzed theoretically the Ti 2p X-ray photoemission spectra (XPS) plus the resonant improvement of valence photoemissionat the https://okada4dsg.com/
