为了提高国际聚变材料辐照设施中将用作中子源的Li-nat（d,xn）反应中子发射光谱的数据精度，作者在日本东北大学的AVF回旋加速器（K = 110） Jacility上测量了40 mev氘核轰击的厚锂和薄锂靶的中子发射光谱。用飞行时间法测量了从0到110度的9个实验室角度，使用波束摆动系统和良好准直的中子飞行通道，使用双增益法测量了几乎整个次级中子的能量范围。获得的数据揭示了发射光谱的形状和角度依赖性，直到称为“高能尾”的高能区域。实验结果与其他实验数据和计算结果进行了比较。
To improve the data accuracy of the neutron emission spectra of the Li-nat(d,xn) reaction that will be used as the neutron source in the International Fusion Materials Irradiation Facility, the authors have measured the neutron emission spectra from thick and thin lithium targets bombarded by 40-MeV deuterons at the AVF cyclotron (K = 110) Jacility of Tohoku University. The neutron spectra were measured at nine laboratory angles between 0 and 110 deg with the time-of-flight method using a beam-swinger system and a well-collimated neutron flight channel, obtained over almost the entire energy range of secondary neutrons using a two-gain method The data obtained revealed the shape and angular dependence of emission spectra up to the high-energy region called a "high-energy tail." The experimental results are compared with other experimental data and calculations.
