Measurement of Angular Distribution and Cross Section For  ̄(58)Ni(n,α)  ̄(55)Fe Reaction at 5.1 MeV
【摘要】 用屏栅电离室测量了入射中子能量为5.1MeV的58Ni(n,α)55Fe核反应的α粒子角分布,238U裂变电离室作中子注量率的测量,测得该能点58Ni(n,α)55Fe的总截面为(47.4±5.0)mb.用中国核数据中心推荐的理论计算程序UNF计算了在1—8MeV能区58Ni(n,p)58Co,58Ni(n,α)55Fe的反应截面和入射中子能量为5.1MeV的58Ni(n,α)反应角分布.理论和测量数据的比较说明,用复合核模型来描写该能点的角分布是可行的.
【Abstract】 The measurement of 58Ni(n,α) 55Fe angular distribution using a gridded-ionization chamber at incident energy 5.1MeV was. carried out. Using fission chamber of 238U to determine neutron fluency, 47.4±5.0 mb of cross section was obtained for 58Ni (n,α) 55Fe. Comparison between experiment and theoretical calculation supports that angular distribution of 58Ni(n, α) 55Fe at neutron energy of 5.1MeV can be described by the model of compound nucleus.
