At the Institute of Physics and Nuclear Engineering in Bucharest a 9 MV FN Tandem accelerator can provide a wide variety of stable isotopes as projectiles, mainly used for nuclear structure physics and nuclear reaction physics experiments.

The main device for gamma ray spectroscopy is the RoSphere detector array, typically in a mixed configuration of high-purity germanium (HPGe) and cerium-doped lanthanum-bromide (LaBr3:Ce) detectors. This detector setup makes it possible to study gamma-gamma coincidences and determine the lifetimes of excited nuclear states with the fast electronic scintillation timing technique (FEST) in the range of a few ten ps to ns or the Doppler-shift attenuation method (DSAM) in the fs to ps range. Furthermore a plunger device is available to measure lifetimes with the recoil-distance Doppler-shift (RDDS) technique (ps range).

Previous experiments:

  • Shape-phase transition at 98Zr – Measurement of excitation function for a future Plunger experiment (2017)
  • Lifetime measurement of short-lived states of 150Gd (2015)
  • Search for a new signature for a quantum shape-phase transition. FEST lifetime measurement of 152Gd (2014)
  • Precision Half-life Measurements of Excited States in 146Sm (2014)
  • Fast Timing Lifetime Measurements of 2+1 States in Hf Isotopes (2013)
