Abstract
COLEGRAM, the new LPRI fitting program processes experimental photon s pectra obtained with semi-conductor detectors. It is mainly characteri sed by its ability to model different peak shapes in the same region o f interest, and to use individual parameters for each peak, including the natural photon Linewidths. Its fast fitting algorithm allows the p rocessing of complex spectra with an appreciable gain in time. As an i llustration, it is applied to processing uranium spectra to give emiss ion probabilities in the complex low-energy region where there are bot h gamma- and K X-rays.
