【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.更多还原

【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.更多还原
