Abstract

The Moessbauer line broadening method for the determination of Lamb-Moessbauer factors f_LM cannot be applied directly in the determination of the probability of the resonant absorption f_LM for single-crystalline absorbers with quadrupole splitted Moessbauer spectra. The line width Γ_exp for single crystals with quadrupole splitted Moessbauer spectra has been computed for various absorber thicknesses. The polarization effects are important and have been taken into account. The linear dependence has been adapted for Lamb-Moessbauer factor measurements by introducing a polarization-dependent coefficient. This method has been tested on measurements of guanidinium nitroprusside (GNP) (CN₃H₆)₂[Fe(CN)₅NO] single crystals.
