【摘要】 本文用活化法以27Al(n,α)24Na 反应截面为中子注量标准,测得的14.9 MeV 中子65Cu(n,2n)54Cu 和46Ti(n,p)46Sc 反应截面分别为9334±32和297±10mb,测得的14.62MeV中子63Cu(n,α)60Co 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.

【Abstract】 The cross sections for the reactions 65Cu(n,2n)64Cu and 46Ti(n,p)46Sc at 14.9 MeV and the reaction 63Cu(n,α)60Co 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 for65Cu(n,2n)64Cu,46Ti(n,p)46Sc and63Cu(n,α)60Co reactions,respectively.The measure-ments were relative to the well-known cross sections for the reaction27Al(n,α)24Na.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.
