In this work an approach is proposed to the analysis of directional angular correlation data in which the function W(θ) used to fit the experimental data already includes the relations between the Akk parameters and the mixing ratios (δ), so that the angular correlation function is fitted explicitly in terms of the mixing ratio of the transition of interest; the normalization factor that arises from the fit can also be used, under certain situations, to determine the intensity of one of the transitions. In order to verify the usability and consistence of this method, some well-determined cascades from 152Eu and 60Co standard sources, as well as from the β- decay of 193Os, were analyzed, and the results compared to the literature values, allowing for a discussion of the performance of this approach.
