摘　　要：The experiment was performed with the fast neutron multi-detector time-of-flight (TOF) spectrometer at the HI-13 tandem accelerator. Three BC501A neutron detectors with the size ofThe experiment was performed with the fast neutron multi-detector time-of-flight （TOF） spectrometer at the HI-13 tandem accelerator. Three BC501A neutron detectors with the size of φ180 mm×100 mm were used to detect the scattered neutrons. The source neutron fluence was monitored with a small neutron detector during the experiment. Twelve angles of neutron emission spectra were measured. The flight path is about 6 m. The source neutrons were produced by D（d, n） reaction. The measured data were analyzed by detailed Monte-Carlo simulations to do the corrections for flux attenuation, multiple scattering, and finite geometry. The measured results were compared with the other measurements and the evaluated data. Fig. 1 shows part of the measured results.
