Abstract
Energy calibration of SI detectors used in electron spectroscopy 13 commonly performed with conversion electron sources or monoenergetic electrons beams, which are preferred against beta emitters due to the problems arising from their continuous spectra. This paper presents a simple calibration procedure for a PIP-type silicon detector, using 14C, 147Pm, 99{sup T}c and 45Ca sources, that is based on the correspondence between the average channel observed in the experimental spectrum and the mean energy evaluated from the theoretical Fermi distribution for each nuclide. First, a method for evaluating the average channel in the experimental spectrum distorted by the electronic noise is described and its uncertainty estimated. Then, the channel-energy relation ship is established by least squares fitting modified to account for uncertainties in both variables.The calibration has been successfully verified with 147Pm and '09cd sources, showing discrepaneles not greater than 2.5%, within the uncertainties due to the detector resolution and the sources features.
