| Zusammenfassung | Neutron scattering cross sections were determined experimentally for more than ten elements in the energy region between 8 and 14 MeV. Comprehensive measuring and data analysis methods were elaborated to obtain cross sections with the highest precision presently possible. The experimental procedure was extended in such a way that cross sections of the complete neutron emission spectrum ranging down to the energy of 1.5 MeV could be derived, thus overcoming the problems usually arising when a nonmonoenergetic neutron source is applied. Typical results are selected for discussion and comparison with the results of other authors and with results taken from several libraries of evaluated neutron data. |
