HyperGam-U was recently developed to determine uranium enrichment based on g- and Xrayspectroscopy analysis. The XKa region of the uranium spectrum contains 13 peaks for235U and 238U and is used mainly for analysis. To describe the X-ray peaks, a Lorentzianbroadened shape function was used, and methods were developed to reduce the number offitting parameters for decomposing the strongly overlapping peaks using channel-energy,energy-width, and energy-efficiency calibration functions. For validation, eight certifiedreference material uranium samples covering uranium enrichments from 1% to 99% weremeasured using a high-resolution planar high-purity germanium detector and analyzedusing the HyperGam-U code. When corrections for the attenuation and true coincidencesumming were performed for the detection geometry in this experiment, the goodness offit was improved by a few percent. The enrichment bias in this study did not exceed 2%compared with the certified values for all measured samples.
