摘要：

We present an effective direct extraction method for hyperfine parameter distributions based on Bayesian inference theory with free-form model and give an example of application to quadrupole splitting distribution analysis in an Fe-57 Mossbauer spectrum of an Fe3+-chlorite. The technique gives a unique solution to the distribution with arbitrary shape and is not sensitive to the elemental doublet parameters. In addition full error analysis of the distribution is obtained for the first time in Mossbauer spectroscopy.
