Abstract
The method of small-angle neutron scattering has been used to investigate the samples of pure nickel before and after irradiation with fast neutron fluences of Φ = 1018, 1019, and 1020 cm−2 (E n ≥ 0.1 MeV). It has been found that the substructure of the samples consists of vacancy clusters with two characteristic sizes of 2.5–4 and ∼7 nm. The sizes of precipitates weakly depend on fast neutron fluence. The magnitude of their density is on the order of 1022 and 1019 m−3, respectively, and increases by three to ten times as the fluence grows.
