摘要：
In this study it is developed a model for the detailed and automatic study of the alpha-particle spectra coming from detection systems. The fitting of a typical shape of the alpha peak is performed by a Gaussian function for the right side of the peak and a sum of two Gaussian functions for its left tail. The model takes into account the entire spectrum background and, particular attention is posed to the analysis of overlapped peaks, background noise and peaks with low statistic counting. The effectiveness of the proposed model is supported by several tests.
