N=90 region: The decays of {152m,g}Eu to 152Sm

The decays of Eu-152(m,g)-> Sm-152 have been studied by gamma-ray spectroscopy using the 8 pi spectrometer, an array of 20 Compton-suppressed Ge detectors. Very weak gamma-decay branches in Sm-152 were investigated through gamma-gamma coincidence spectroscopy. All possible E2 transitions between states below 1550 keV with transition energies >130 keV are observed, including the previously unobserved 2(3)(+)-> 0(2)(+) 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 Sm-152 and the N=90 isotones.
