Resumo
In all applications of gamma-ray spectroscopy, one of the most important and delicate parts of the data analysis
is the fitting of the gamma-ray spectra, where information as the number of counts, the position of the centroid
and the width, for instance, are associated with each peak of each spectrum. Theres a huge choice of computer
programs that perform this type of analysis, and the most commonly used in routine work are the ones that
automatically locate and fit the peaks; this fit can be performed in several different ways - the most common
are either to fit a Gaussian function to each peak or simply to integrate the area under the peak, but some
software go far beyond and include several small corrections to the simple Gaussian peak function, in order to
compensate for secondary effects. In this work several gamma-ray spectroscopy software are compared in the
task of finding and fitting the gamma-ray peaks in spectra taken with some calibrated standard sources. The
results allow for a discussion on the performance of each software in the tasks of identifying and determining the
correct area of the gamma-ray peaks, as well as on the advantages and difficulties in using automatic programs
when comparing with a manual peak-fitting software, used as reference.
