摘要

利用屏栅电离室对1.05、1.54及2.25MeV中子6Li（n

t）4He反应的微分截面与截面进行了实验测量。采用氚固体靶的T（p

n）3He反应产生准单能中子

用相对效率已知的BF3长中子管和238U裂变片相结合来测定绝对中子通量。将测量结果与已有数据进行了比较

1―2MeV能区6Li（n

t）4He反应截面的分歧在一定程度上得到了澄清。

Abstract

By using a gridded ionization chamber

the differential cross sections and angle integrated cross sections of the 6Li(n

t)4He reaction were measured at neutron energies of 1.05

1.54 and 2.25 MeV. Neutrons were produced through the T(p

n)3He reaction. The absolute neutron flux was determined through a relatively calibrated BF3 long counter and a 238U foil. Present results are compared with existing data

and the discrepancies for the cross sections of the 6Li(n

t)4He reaction in the 1―2 MeV energy range are clarified to some extent.
