用屏栅电离室对3.67MeV与4.42MeV中子6Li(n，t)4He反应微分截面进行了测量。利用氘气体靶通过D(d，n)3He反应产生中子,用BF3和液闪探测器(NE213)进行相对中子通量监测,绝对中子通量用238U(n，f)与H(n，p)反应来刻度。测量结果表明,氚的质心系微分截面在中子能量为3.67MeV时很接近90°对称,而到4.42MeV时则明显前倾。%By using a gridded ionization chamber，the differential crosssections and angle integrated cross sections for the 6Li(n，t)4He reaction were measured at neutron energies of 3.67 and 4.42MeV. The neutrons were produced through D(d，n)3He reaction by a deuteron gas target. Absolute neutron flux was determined through 238U(n，f) and H(n，p) reactions. At 3.67MeV the differential cross section for triton is almost 90° symmetric but it is obviously forward peaked at 4.42MeV in the center-of-mass reference system.
