Abstract
Zusammenfassung Using a fast time-of-flight spectrometer, the neutron spectra d 2 σ/ d Ω d E of the reaction 2H(n, 2n)H have been measured at an incident energy of 14.1 MeV. The investigation was carried out for eight angles lying between 7.5° and 75°, in the energy range of 2 MeV and the upper limit of the continuous distribution. At small angles, the peaks appearing in the central part and at the upper limit of the spectrum can be explained by means of the final state interaction between the break-up nucleons. The structure of the spectrum decreases at larger angles, the peaks disappearing almost completely for θlab > 30°. The differential break-up cross section dσ/dΩ is obtained by integration of the break-up spectra over the given energy range. For the emission of neutrons in the forward hemisphere, the total cross section was found to be σV = 255±30 mb. The results have been compared with various theoretical and experimental values.
