DETERMINATION OF THE AVERAGE NEUTRON ENERGY USING CROSS SECTION RATIO OF ^(58)Ni(n, p) ^(58m+g)Co and ^(58)Ni(n,2n) ^(57)Ni REACTIONS

本文叙述了用两个硅半导体探测器和^(58)Ni(n,p)^(58g+m)Co与^(58)Ni(n,2n)^(57)Ni反应截面比定D-T中子的平均能量的方法,得到了该截面比与中子能量的关系曲线并与所引文献中的结果进行了比较.

The method of determination for average neutron energy from D-T reaction by using two si(?)on semiconductor detectors and the cross section ratios of ^(59)Ni(n,p) ^(58m+g)Co and ^(58)Ni (n,2n) ^(57)Ni r(?)actions is described. The plot of the cross section ratio against the neutron (?)gy has been obtained. The results have been compared with existing data.
