In this work, a peak analysis and unfolding method for low energy gamma-ray spectroscopy is introduced, which is based on extensive Monte Carlo simulations to determine the peak integral of a photopeak.
Within the present work a peak analysis and unfolding method for low energy gamma-ray spectroscopy is presented. This method can be used to facilitate the determination of the peak integral of a photopeak, when Ge X-ray escape peaks contaminate the latter and in parallel the source activity and the emission rate of the recorded photons which produce the escape peaks are unknown. It is based on extensive Monte Carlo simulations of the spectra by taking the full advantage of power and accuracy provided by the GEANT4 simulation toolkit.
