摘要：

Fission neutron spectrum averaged cross sections have been measured for the threshold reactions Ni-58(n, 2n)Ni-57, I-127(n, 2n)I-126, Mn-55(n, 2n)Mn-54, Cu-63(n, alpha)Co-60 and P-31(n, p)Si-31, by the activation technique using high-resolution gamma-ray spectroscopy. The fast neutron spectrum at the irradiation position has been characterized by using an additional set of activation foils. The results are presented with a complete uncertainty covariance matrix and are compared with evaluated values and previous measurements.
