The paper shows the possibility of reconstruction of the distribution of hyperfine field parameters without prior assumptions concerning correlations between parameters. The method used is the maximum entropy method and the distributions considered concern the magnetic field and isomer shift. The results obtained are very encouraging and show the feasibility of the proposed method.
