Abstract

The decays of Eu152m,g→Sm152 have been studied by γ-ray spectroscopy using the 8π spectrometer, an array of 20 Compton-suppressed Ge detectors. Very weak γ-decay branches in Sm152 were investigated through γ-γ coincidence spectroscopy. All possible E2 transitions between states below 1550 keV with transition energies >130 keV are observed, including the previously unobserved 23+→02+ 401 keV transition. The results, combined with existing lifetime data, provide a number of new or revised E2 transition strengths which are critical for clarifying the collective structure of Sm152 and the N=90 isotones.
