AbstractAbstract
[en] A method based on X-and γ-rays spectrometry with Ge detectors was used to determinate and improve the photon emission probability values in the decay of 169 Yb and 226 Ra. As an additional contribution, it applies techniques of peak deconvolution in complex regions of the spectrum associated to the knowledge of spectral information about characteristic X-rays of the present like interferent peaks that allows to distinguish and obtain the probability values of the XK lines. From the obtained experimental results, their values show an improvement or agree with those announced data. It can also be seen that overall, a good and compatible estimation of the uncertainties when compared to the newly published values. (author)
