Characteristics Optimization of the Resonant Detector for Mössbauer Spectroscopy Using Resonance 57Fe

This paper considers the converter materials having different mean thickness, isomeric chemical shift, and various cationic surroundings of the iron atoms in the converter matrix for resonance detectors. The influence of the converter material parameters on the characteristics of the Mössbauer spectra taken by the resonance detector has been estimated. The value of resonance absorption, experimental linewidth, and the measurement time of the Mössbauer spectra has been calculated taking into account the material converter parameters. It has been found that beryllium ferrocyanide with efficient thickness equal to 2 is the most appropriate converter for emission experiments, and potassium-magnesium ferrocyanide with effective thickness equal to 4 proves to be optimal for transmission Mössbauer experiments.
