Analysis of the local atomic structure of manganese and its oxides by extended energy loss fine structure spectroscopy

A technique for determining parameters of the local atomic structure of a manganese-oxygen system by the extended energy loss fine structure method has been proposed. Experimental extended energy loss fine structure spectra of the clean surface of metallic manganese and its stoichiometric oxides have been measured. Normalized oscillating portions have been separated from the experimental spectra and analyzed by solving the inverse problem using the Tikhonov regularization. The parameters of the local atomic structure of the objects under study, i.e., coordination numbers, bond lengths, and their variance parameters, have been determined.
