Description

To investigate the accuracy of the calibration of the HPGe detectors using an uncalibrated complex gamma cascade emitting source and the sum-peak method, Monte Carlo simulations were conducted. It was shown that accuracy below 5% is achievable for a 133Ba source, only if the spectral data are corrected for angular correlations even at short distances from the detector endcap.
