摘要：

Neutron energies and angular distributions were measured in 9 Be(a,n) 12 C reaction for a energies of 5.5 and 6.5 MeV. Three major neutron groups were observed in the spectrum, which correspond to the ground and first two excited states of 12 C. Measured data could only be explained by the TALYS calculation if reaction at more than one location within the target is considered for a given beam energy. The preferred locations are driven by the resonance energy levels existing in 13 C. Neutron yield due to the 9 Be breakup process was determined which is found to be 12.6 +/- 0.2% and 18.4 +/- 0.5% of the total reaction cross-section for 5.5 and 6.5 MeV respectively.
