Abstract：
The neutron emission double-differential cross sections(DDXs) of n+⁹Be and ^6,7Li were measured at incident neutron energies of 8.17 and 10.27MeV. At 10.27MeV, the influence of breakup source neutrons from D(d, np) reactions was eliminated by using the combination of abnormal and normal fast neutron TOF spectrometers. The measured TOF spectra were analyzed by detailed Monte-Carlo simulation and the DDXs were determined by comparing the measured TOF spectra with simulated ones. The cross sections were normalized to n-p(normal geometry measurement) or n-C(abnormal geometry measurement) scattering measurement. The measured results were compared with the evaluations and the other measurements. A theoretical model based on the Hauser-Feshbach and exciton model for light nuclei was used to describe the double-differential cross sections of n+^6,7Li. Good agreement between theoretical calculation and measurement has been obtained.
