Evaluation of 169Yb decay data

This evaluation of the complete decay scheme of 169Yb sums up the recent measurements carried out during an international exercise in which 11 laboratories were involved, and also takes into account other independent experiments. As a result of the numerous high-quality measurements available, the decay scheme is shown to be highly consistent. The half-life is determined to be 32.018 (5) d, and the emission probabilities of the two reference γ lines of 198 and 307 keV are recommended to be 35.93 (12)% and 10.046 (45)%, respectively.
