Abstract
The main purpose of the following report is the study of a generation method of {gamma} spectra corresponding to any energy, from a library of some basic spectra. Then we point out how to establish the decay scheme of a radio-nuclide, in using an accurate analysis of full-energy peaks which appear in its complex spectrum, followed by a generation of plain spectra corresponding to the energies of the different transitions, and ending with a least-squares fitting procedure of the complex spectrum. The accuracy of the process is examined comparing the calculated spectra to the ones issued from two kinds of spectrometers (Na I(Tl) and Ge(Li)). The method is then applied to the study of {sup 134}Cs and {sup 95}Zr - {sup 95}Nb. (authors) [French] Le present rapport a pour principal objet l'etude d'une methode de generation de spectres {gamma} correspondant a n'importe quelle energie, a partir d'une bibliotheque de quelques spectres de reference. On montre ensuite comment on peut etablir le schema de desintegration d'un radionucleide, a l'aide d'une analyse precise des pics d'absorption totale apparaissant dans son spectre complexe, suivie d'une generation des spectres simples correspondant aux energies des diverses transitions, et en terminant par une decomposition du spectre
