T(d,n)~4He反应的中子能谱的测量和模拟计算

The Measurements and Simulations of the Spectra of Neutrons Produced via the T(d, n)~4He Reaction

本文描述用飞行时间谱仪对T(d,n)~4He反应的α关联中子能谱和角分布的测量,以及介绍对这些中子能谱的蒙特卡罗模拟。在计算中考虑了氘在氚-钛靶的多次散射。对发射中子谱自寺和关联中子平均能量的计算结果分别与Pavlik等人的计算结果和我们的实验结果很好地符合。

The measurements with the time-of-flight spectrometer both the energy spectra and the anguar distribution of the neutrons which are produced via the T(d, n)~4He reaction and also related to α particles are discribed, and the Monte-Carlo simulations of the energy spectra of these neutrons are presented. In the calculation the multiscattering of the deuterons in the T-Ti target had been concerned. Our calculating results of the emitting neutron spectra and the average energy of related neutrons are respectively in good agreement with the calculating results of Pavlik et al. and our experimental result.
