L. Zikovsky, Use of the Pearson IV function to describe the dependence of detection efficiency of Ge detectors on gamma-ray energy, J RAD NUCL, 247(2), 2001, pp. 411-412
2000 analytical functions were fitted to the measured gamma-ray detection e
fficiencies of a Ge detector for a small irradiation vial located at the cl
osest distance from the detector. Among these. the Pearson IV function, gav
e the best fit. The measured and calculated efficiencies were compared for
50 determinations (for energies which varied between 61 and 2754 keV) and a
relative a standard deviation of 8.3% was obtained.
