The decays of {sup 152}Eu{sup m,g}{yields}{sup 152}Sm 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 {sup 152}Sm 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{sub 3}{sup +}{yields}0{sub 2}{sup +} 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 {sup 152}Sm and the N=90 isotones.
