Description
Nuclear lifetimes are one of the key observables providing a direct access to the structure of excited states. The commonly used technique that allows for their extraction is the fast-timing method which benefits from the use of fast scintillators. However, it also requires large datasets collected by highly granular setups. This limitation can be overcome by using a strong flux of thermal neutrons with a high gamma-detection efficiency setup. This enables population of excited states either by a thermal neutron capture or in fission.
In my talk I will present FIPPS, Fission Product Prompt gamma-ray Spectrometer, a permanent gamma-ray detection setup at the Institut Laue-Langevin in Grenoble, France. I will discuss its capabilities, results from recent experimental campaigns and future plans. The particular focus will be put on the preliminary results from the most recent fast-timing campaign.
