Abstract:
Cross sections of the 58,60,61 Ni( n , α ) 55,57,58 Fe reactions were measured at 8.50, 9.50 and 10.50 MeV neutron energies based on the HI-13 tandem accelerator of China Institute of Atomic Energy (CIAE) with enriched 58 Ni, 60 Ni, and 61 Ni foil samples with backings. A twin gridded ionization chamber (GIC) was used as the charged particle detector, and an EJ-309 liquid scintillator was used to obtain the neutron energy spectra. The relative and absolute neutron fluxes were determined via three highly enriched 238 U 3 O 8 samples inside the GIC. The uncertainty of the present data of the 58 Ni( n , α ) 55 Fe reaction is smaller than most existing measurements. The present data of 60 Ni( n , α ) 57 Fe and 61 Ni( n , α ) 58 Fe reactions are the first measurement results above 8 MeV. The present experimental data could be reasonably reproduced by calculations with TALYS-1.9 by adjusting several default values of theoretical model parameters.
