| Abstract: | The specific activity of a 169Yb solution was determined at the PTB by 4πEC-γ-coincidence measurements and by 4πγ-counting with a relative standard uncertainty of 0.1%. Based on a simplified decay scheme with 21 gamma transitions, relative gamma-ray emission probabilities measured at the PTB and data from other authors, a consistent set of decay data for the decay of 169Yb was calculated. The absolute emission probability of the 198 keV gamma rays was determined to be (0.3591±0.0013) photons per disintegration. |
