Abstract: Experimental activities at JRC-Geel on prompt-fission-neutron (PFN) emission in response to OECD/NEA nuclear data requests are presented in this report. Specifically, investigations of PFN emission from the reaction 235U(n,f) in the region of the resolved resonances are presented. The experiment employs a scintillation detector array for neutron detection, while fission fragment properties are determined via the double kinetic energy technique using a position sensitive twin ionization chamber. This setup allows us to study several correlations between properties of neutron and fission fragments simultaneously. Results on PFN correlations with fission fragment properties from the present study differ significantly from earlier studies on this reaction, induced by thermal neutrons.
