Description
The decays of 152Eum,g→152Sm 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 152Sm 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 152Sm and the N=90 isotones
