Abstract The electron-capture decay of Gd151 was investigated by means ofγ- andγ-γ-coincidence spectrometry, using scintillation counters. Besides the knownγ-rays of 22 kev, 154 kev, 175 kev, 244 kev and 308 kev additionalγ-transitions with energies of 107 kev and 350 kev could be assigned to the decay of Gd151.γ-γ-coincidence measurements showed the following cascade transitions: (107 kev–244 kev), (154 kev–175 kev–22 kev) and (308 kev–22 kev). TheK-conversion-coefficients of several transitions were determined by comparing theγ-intensities and the previously known conversion electron-intensities, using a direct measurement of theK-conversion-coefficient of the 175 kev-transition by a delayed coincidence-experiment as a normalization of the relative intensities. With the available information a level-scheme for Eu151 is proposed.
