Analysis of Neutron Double-Differential Cross Section of n＋^14N at 14.2 MeV

Abstract By using a new reaction model for light nuclei, the double-differential cross section of n ^14N reactions at En=14.2 MeV has been analyzed. In the case of n ^14N reactions, the reaction mechanism is very complex, there are over one hundred opened partial reaction channels even at incident energy En=14.2 MeV. In this paper the opened reaction channels are listed in detail. With LUNF code the model calculation is performed to analyze the doubledifferential cross sections of total outgoing neutron. The calculated results agree fairly with the experimental data. The results indicate that the pre-equilibrium mechanism dominates the whole reaction processes, and the recoil egect in light nuclear reactions is essentially important. 5He emission has been considered, but it is only a small contribution to thedouble-differential cross section at incident energy En=14.2 MeV.

Analysis of Neutron Double-Differential Cross Section of n+14N at 14.2 MeV

By using a new reaction model for light nuclei, the double-differential cross section of n+¹⁴N reactions at E_n=14.2 MeV hasbeen analyzed. In the case of n+¹⁴N reactions, the reaction mechanism is very complex, there are over one hundred opened partial reaction channels even at incident energy E_n=14.2 MeV. In this paper the opened reactionchannels are listed in detail. With LUNF code the model calculation isperformed to analyze the double-differential cross sections of totaloutgoing neutron. The calculated results agree fairly with the experimental data. The results indicate that the pre-equilibrium mechanism dominates the whole reaction processes, and the recoil effect in light nuclear reactions is essentially important. ⁵He emission has been considered, but it isonly a small contribution to the double-differential cross section at incidentenergy E_n=14.2 MeV.
