By using a new reaction model for light nuclei,the double-differential cross section of n+~(14)N reactions atE_n=14.2 MeV has been analvzed.In the case of n+(14)N reactions,the reaction mechanism is cery complex,there areover one hundred opened partial reaction channels even at incident energy En=14.2 MeV.In this paper the openedreaction channels are listed in detail. With LUNF code the model calculation is performed to analyze the double-differential cross sections of total outgoing neutron. The calculated results agree fairly with the experimenal data.Theresults indicate that the pre-equilibrium mechanism mechanism dominates the whole reation processes,and the recoil effect in lightnuclear reactions is essentially important.~5He emission has been considered,but it is only a small contribution to thedonble-differential cross section at incident energy En=14.2 MeV.
By using a new reaction model for light nuclei, the double-differential cross section of n + ~ (14) N reactions at E_n = 14.2 MeV has been analzed in the case of n + (14) N reactions, the reaction mechanism is cery complex, there areover one hundred opened partial reaction channels even at incident energy En = 14.2 MeV. This paper opened opeaction channels are listed to analyze the double-differential cross sections of total outgoing neutron. calculated results agree fairly with the experimenal data. The results indicate that the pre-equilibrium mechanism mechanism dominates the whole reation processes, and the recoil effect in light nucleucleation reactions is essentially important. ~ 5He emission has been considered, but it is only a small contribution to thedonble-differential cross section at incident energy En = 14.2 MeV.
