Abstract

In this article, the X-ray and gamma-ray coincidence summing effect in (152)Eu is studied. Coincidence summing corrections and peak and total efficiencies of point and volume sources were determined using the direct matrices multiplication (DMM) method. The theoretically evaluated peak count rates were found to be in good agreement with the experimentally obtained values. Validation was performed by comparing the calculated efficiency curves and the corresponding correction factors with the results obtained using GESPECOR 4.2 software.

Keywords: (152)Eu; Coincidence summing corrections; Gamma-ray spectrometry.
