摘要：

A new method is proposed to evaluate the hyperfine parameter distribution in Mossbauer spectra of silicate glasses. The method assumes a distribution of isomer shift and quadrupole splitting with a two-dimensional Gaussian shape. Application of the method to Mossbauer spectra of CaO-SiO2-Fe-O glasses containing different redox ratios, Fe3+/Fe2+, is discussed. It is shown that the two-dimensional Gaussian distribution method leads to a very good description of the data with a relatively small number of free parameters.
