Investigation of the Mössbauer Spectrum Quality as a Dependence on the Frequency of the Velocity Signal

This paper is focused on a quality characterizing the Mossbauer spectra measured for various frequencies of the velocity signal. Standard electromechanical double‐loudspeaker drive and digital PID velocity controller were used for calibration spectra measurement in the frequency interval from 4 up to 100 Hz. Several parameters were evaluated for recommendation of the suitable velocity signal frequency.
