The Cross Section of the 16O(n,alpha) 13C Reaction in the MeV Energy Range
A novel spectrometer was developed and used to measure the cross section for the 16O(n,alpha) reaction at IRMM. The basic parts of the new instrument are an ionisation chamber, a gas oxygen target, and signal digitisation. It is shown that simultaneous digitisation of the anode and cathode signals allows an effective background suppression and the accurate determination of the number of reaction events and the number of atoms in the gas target. Cross section values for the 16O(n,alpha) reaction measured in the energy range 3.95-9.0MeV are presented. None of the existing nuclear data libraries describes well the IRMM data in the entire energy range.
