Simultaneous measurement of the neutron capture and fission yields of 233-U

Abstract

We have measured the neutron capture and fission cross section of 233U at the neutron time-of-flight facility n TOF at CERN in the energy range from 1 eV to 1 MeV with high accuracy by using a high performance 4π BaF2 Total Absorption Calorimeter (TAC) as a detection device. The method, based on the TAC energy response study, allowing to disentangle between γ’s originating from fission and capture will be presented as well as the first very preliminary results.
