Description
The energy of the γ-ray de-exciting the 5/21+ level of 137Cs was determined with high accuracy in an isotope separator on-line experiment. The result is (455.490+-0.003) keV as referred to the 198Au energy standard of (411.794+-0)keV. Knowledge of this energy is important for the determination of muonic X-ray energies in Ba as a test of the validity of quantum electrodynamics. In addition, the 41+→21+ transition in 138Cs was determined to be (462.785+-0.005)keV. (Auth.)
