Results and discussion. The XANES spectra of all zinc materials in this study had principal K-edge peak energies between 9660.5 and 9666.0 eV.This peak results from the excitation of an electron from a 1 s inner orbital to higher-energy orbitals as a result of interaction with a synchrotron-generated X-ray. Subsequent decay of higher-energy …
