|Abstract:||In the frame of the exploratory research initiative of the JRC a new pulsing device has been installed at the Van-de-Graaff of the IRMM to produce pulsed quasi mono-energetic neutron beams in the MeV range. The pulse width may be tuned from 10 mus up to several hundreds of mus with a repetition rate between 1 Hz and 5 kHz. The aim is to study the decay of short-lived activation products between pulses in an essentially neutron-free environment. In a first application the shape isomer in 239U is searched, for which a decay half-life probably much longer than a few tens of mus has been predicted in literature. The new facility will be presented together with first results on the shape-isomer search, and some possible applications will be discussed.|
