摘 要:本文用活化法以^(27)Al(n,α)^(24)Na 反应截面为中子注量标准,测得的14.9 MeV 中子^(65)Cu(n,2n)^(54)Cu 和^(46)Ti(n,p)^(46)Sc 反应截面分别为9334±32和297±10mb,测得的14.62MeV中子^(63)Cu(n,α)^(60)Co 反应截面值为42.3±1.5 mb.单能中子由 T(d,n)~4He 反应获得,中子能量是用铌锆截面比法测定的.在文中还把本文的结果与其他一些作者的数据进行了比较.The cross sections for the reactions ^(65)Cu(n,2n)^(64)Cu and ^(46)Ti(n,p)^(46)Sc at 14.9 MeV and the reaction ^(63)Cu(n,α)^(60)Co at 14.62 MeV have been measured by the activa-tion method.The values of 933±32.297,297±10 and 42.3±1.5 mb were obtained for^(65)Cu(n,2n)^(64)Cu,^(46)Ti(n,p)^(46)Sc and^(63)Cu(n,α)^(60)Co reactions,respectively.The measure-ments were relative to the well-known cross sections for the reaction^(27)Al(n,α)^(24)Na.Mono-energetic neutron was obtained from the T(d,n)~4 He reaction.The neutron energywas determined by the activity ratio of Zr to Nb foils.The results are compared with thedata published.
