DDEP re-evaluation of the radioactive decay scheme of $^{137}$Cs
Résumé
A complete re-evaluation of the $^{137}$Cs $\beta^-$ decay scheme has been performed within the scope of the Decay Data Evaluation Project (DDEP), taking full advantage of the most recent measurements. An evaluated half-life of 30.018 (22) years is recommended, along with a full revision of the $\beta^-$ decay branching ratios that also results in a re-evaluation of the absolute emission probability of the 662-keV gamma ray to give a value of 85.01 (20)%. Recommendations for new measurements are also suggested.
