Compilation of errors in nuclear parameters for radionuclide Eu-152

Abstract Certain irregularities have been observed in the formation of probability matrices when applying our method for calculating the coincident summing effects occurringin the gamma spectroscopy of radionuclides. They have to do with the fact that, at certain energy levels, transition intensities are not balanced. As this affects the accuracy of our calculation, we have examined the source of those irregularities. This paper presents comments on the evaluation of the 152 Eu decay data. The paper offers an analysis of the errors and mistakes that the evaluators have made, in order to facilitate the future work in gamma spectroscopy.
