Abstract
The spectrum of the internal bremsstrahlung accompanying the electron-capture decay of has been measured in coincidence with the 477-keV rays. From the extrapolated endpoint energy of the spectrum, the transition energy to the first excited state of was determined to be 395 ± 25 keV. The intensity of the internal bremsstrahlung in the energy range from 120 to 360 keV was determined to be (5.45 ± 1.1) × per ordinary nonradiative capture (based on a theoretically predicted ratio of 12.4 × ) as compared with the value of 7.86 × predicted by the theory of Martin and Glauber.
