| Abstract: | The Mössbauer line broadening method for the determination of Lamb–Mössbauer factors fLM cannot be applied directly in the determination of the probability of the resonant absorption fLM for single-crystalline absorbers with quadrupole splitted Mössbauer spectra. The line width Γexp for single crystals with quadrupole splitted Mössbauer 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–Mössbauer 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. |
