In n+~(10)B reactions, ~5He cluster emission has been discussed with the updated level scheme and the new optical model parameters. In this paper the reaction channels related to ~5He emission are listed in detail. By using the new reaction model for light nuclei, the double-differential cross sections of total outgoing neutrons for n +~(10) B reactions at E_n=14.2 MeV have been calculated, and the results agree fairly well with the measurements. Particularly, in the energy-angular spectra the contribution from the ~5He-emission to the total outgoing neutron double-differential cross sections has also been analyzed, and the partial energy-angular spectra of 60° at E_n=14.2 MeV have been given. The calculated results indicate that once the ~5He emission is taken into account, the fitting with the double-differential measurements of total outgoing neutrons at the low energy region could be improved. Therefore, to consider the ~5He emission properly in the reaction processes of light nuclei is necessary.
In n + ~ (10) B reactions, ~ 5He cluster emission has been discussed with the updated level scheme and the new optical model parameters. In this paper the reaction channels related to ~ 5He emission are listed in detail. By using the new reaction model for light nuclei, the double-differential cross sections of total outgoing neutrons for n + ~ (10) B reactions at E_n = 14.2 MeV have been calculated, and the results agree fairly well with the measurements. Particularly, in the energy-angular spectra the contribution from the ~ 5He-emission to the total outgoing neutron double-differential cross sections has also been analyzed, and the partial energy-angular spectra of 60 ° at E_n = 14.2 MeV have been given. The calculated results indicate that once the ~ 5He emission is taken into account, the fitting with the double-differential measurements of total outgoing neutrons at the low energy region could be improved. Thus, to consider the ~ 5He emission properly in the reaction processes of light nuc lei is necessary.
