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.
