The new Bucharest multi-detector setup for γ-ray spectroscopy studies — •Sorin Pascu — National Institute for Physics and Nuclear Engineering, Bucharest, Romania

The ROmanian array for SPectroscopy in HEavy ion REactions (ROSPHERE) is a new 4π high-resolution γ-ray detector array which was installed at the Bucharest 9 MV tandem accelerator. The setup consists of up to 25 detectors and it is typically used in a mixed combination of high-purity Ge detectors and fast LaBr₃:Ce scintillation detectors. The total efficiency of the array is close to 3%, balanced between the two type of detectors when used in the usual configuration with 14 HPGe (є ≃1.1%) and 11 LaBr₃:Ce detectors (є ≃1.8%). The multi-detector setup can be coupled with a state of the art plunger device allowing for lifetime measurements by employing the Recoil Distance Doppler Shift (RDDS) or in-beam Fast Electronic Scintillation Timing (FEST) technique. Two recent experiments illustrating the methods are presented.
