The total cross section for fast neutrons of N¹⁴ Kubelka, Werner
The total neutron cross section of N¹⁴ was measured for neutron energies from 3.6 to 4 Mev. A 15-cm.-long liquid Nitrogen cell was irradiated with monochromatic neutrons from the D(d,n)He reaction, going in energy steps of approximately 15 kev. The transmission was measured at each energy, using a propane recoil counter for counting the transmitted neutrons. An identical counter was used at 90° for monitoring. The results appear to confirm Stetter and Bothe's measurements, which were made with a continuous neutron energy distribution.
