摘要：Neutron scattering cross sections have been determined 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 available at the cyclotron of the TOF
spectrometer at PTB, neutrons in the energy range from 6 MeV to 16 MeV can be produced. For
the planned measurements of inelastic scattering cross sections of 206,207Pb in the 2 MeV to
4 MeV region, the implementation of a new neutron source is required.
The 15N(p,n) reaction was investigated with special regard to its suitability as a neutron source
for scattering experiments. Angular distributions were measured at selected energies. The
influence of the target thickness on the energy resolution 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 15N(p,n) reaction as a neutron source in scattering
experiments.
