Abstract
The Non-Destructive Assay (NDA) group at New Brunswick Laboratory (NBL) continues to develop and refine a computerized program ALPHAFIT, a sophisticated peak-fitting routine for use in determining the isotopic abundances of Pu and U samples. The program uses up to seven parameters per peak fit and up to 12 peaks per region of interest to de-convolute typical complicated Pu a spectra. Preliminary results show decent fits for major peaks in the spectrum and calculated isotopic abundances of the major isotopes to ± 4%.
