Abstract
To investigate the possible origins of peak splitting and low energy tails in measured Q spectra of 4\(\pi \) measurements, we introduced a Geant4 simulation to generate alpha-decay events where the energy loss mechanism of alphas and daughter nuclei refers to G4ScreenedNuclearRecoil. The Monte Carlo method with the assumption of incomplete heat release from the source layer to the 4\(\pi \) gold absorber reproduced the characteristics of the measured spectra of various radionuclides in samples that were prepared with different heat-treatment times.
