摘要

The cross sections of (58)Ni(n, p)(58(m+g))Co,(60)Ni(n, p)(60m)Co,(61)Ni(n, p)(61)Co and (62)Ni(n, p)(62m)Co reactions induced by neutrons around 14 MeV were measured using activation technique and a coaxial HPGe gamma-ray detector. The natural nickel foils of 99.9% purity were used as target materials. Fast neutrons were produced by the T(d, n)(4)He reaction. The neutron flux was determined using the monitor reaction (27)Al(n, alpha)(24)Na and the neutron energies were measured with the method of cross-section ratios for (90)Zr(n, 2n)(89)Zr to (93)Nb(n, 2n)(92m)Nb reactions. The results of this work are compared with the collected partial recent data published previously and the estimations obtained from the published empirical formula based on the statistical model with dependence on the Q-value and odd-even effect taken into consideration.
