摘要
本文叙述了从13.50 MeV到14.81 MeV中子能区用活化法相对^(21)Al(n,α)^(24)Na的反应截面,对^(50)Ti(n,α)^(47)Ca、^(48)Ti(n,p)^(48)Sc、^(46)Ti(n,p)^(46)Sc、^(58)Ni(n,2n)^(57)Ni、^(58)Ni(n,p)^(58m+g)Co五个反应截面的测量。并将所得的结果和其他作者的结果进行了比较。
The cross sections for the ^(50)Ti(n, α)^(47)Ca, ^(46)Ti(n, p)^(46)Sc, ^(48)Ti(n, p)^(48)Sc and ^(58)Ni(n, 2n) ^(57)Ni ^(58)Ni(n, p)^(58m+g) Co reactions have been measured by using the activation method rela- tive to the cross sections of the ^(27)Al(n, α)^(24)Na reaction in the neutron energy range of 13. 50--14. 81MeV. The neutron energies were determined by the cross section ratios of the ^(90)Zr (n, 2n)^(89m+g) Zr and ^(93)Nb(n, 2n)^(92m)Nb reactions. The results obtained are compared with the published and to be published data of several authors.
