Abstract
A new model for the description of incoherent peaks observed in energy-dispersive x-ray fluorescence spectra is proposed. The model was derived after a systematic study of peak shapes based on Monte Carlo simulations. The model consists of a Gaussian modified by two exponential tail functions. The model is implemented in a non-linear least-squares fitting procedure and tested on spectra measured with a 109Cd excitation XRF setup using an HPGe detector.
