Neutron scattering cross sections have been determi n d with high precision at PTB for a number of years. So far, primarily the D(d,n) reaction has been used for the production of neutrons. Due to the Q value of +3.27 MeV and the deuteron energies availa ble t the cyclotron of the TOF spectrometer at PTB, neutrons in the energy range f rom 6 MeV to 16 MeV can be produced. For the planned measurements of inelastic scattering cr oss sections of Pb in the 2 MeV to 4 MeV region, the implementation of a new neutron s urce is required. The N(p,n) reaction was investigated with special regar d to its suitability as a neutron source for scattering experiments. Angular distributions w ere measured at selected energies. The influence of the target thickness on the energy res olution and the neutron yield was investigated. Preliminary scattering experiments were carried out in this energy region to identify potential problems in the application of the N(p,n) reaction as a neutron source in scattering experiments.
