摘要

测量了 9Be(α,n)12C反应中α能量为 5.5 和 6.5 MeV 的中子能量和角度分布。光谱中观察到三个主要的中子群，分别对应于 12C 的基态和前两个激发态。只有在给定射束能量的情况下，考虑靶内多个位置的反应，TALYS 计算才能解释测量数据。首选位置是由 13C 中存在的共振能级驱动的。测定了 9Be 分裂过程的中子产率，发现在 5.5 和 6.5 MeV 时，其产率分别为总反应截面的 12.6 ± 0.2% 和 18.4 ± 0.5%。

Investigation of breakup process in 9Be(α,n)12C reaction

Neutron energies and angular distributions were measured in ⁹Be(α,n)¹²C reaction for α 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 ¹²C. 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 ¹³C. Neutron yield due to the ⁹Be 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.
