Choice of the detector scintillation crystal thickness in a spectrometer used for phase analysis of a substance by the gamma-resonance method

A discussion is given of the choice of the thickness of the scintillation crystal in a spectrometer used for phase analysis of a substance by the gamma-resonance method when the concentration of the investigated phase is low and the resonant gamma rays are recorded by measuring the total absorption peak.Translated from Izmeritel'naya Tekhnika, No. 9, pp. 63–65, September, 1995.
