Evaluation of Activation Cross Sections for (n,2n) Reactions on 58, 60, 61, 62, 64, NatNi

Introduction Nickel is a very important structure material in nuclear fusion engineering. The neutron activation cross section are very useful in fusion research and other applications such as radiation safety, environmental, material damage and neutron dosimetry. More efforts are required to identify and resolve the discrepancies in the existing activation cross sections from different laboratories. The natural nickel consists of five stable isotopes. Their abundaces and threshold energies are shown in Table 1.
