    Gamma transition intensity determination using multidetector coincidence data
    2009 - ZAHN, GUILHERME S.; GENEZINI, FREDERICO A.; ZAMBONI, CIBELE B.; CRUZ, MANOEL T.F. da
    This work describes two similar methods for calculating gamma transition intensities from multidetector coincidence measurements. In the first one, applicable to experiments where the angular correlation function is explicitly fitted, the normalization parameter from this fit is used to determine the gamma transition intensities. In the second, that can be used both in angular correlation or DCO measurements, the spectra obtained for all the detector pairs are summed up, in order to get the best detection statistics possible, and the analysis of the resulting bidimensional spectrum is used to calculate the transition intensities; in this method, the summation of data corresponding to different angles minimizes the influence of the angular correlation coefficient. Both methods are then tested in the calculation of intensities for well-known transitions from a 152Eu standard source, as well as in the calculation of intensities obtained in beta-decay experiments with 193Os and 155Sm sources, yielding excellent results in all these cases.
