Description
Nickel foils were irradiated with helium ions up to different doses. The annealing of the samples was studied by positron annihilation lifetime measurements (T.E.M. results will not be discussed in detail). The measurements were performed with different lifetime spectrometers. In the as-irradiated state and during the annealing, two lifetime components were present. Below 800 K, the second lifetime is quite long and is attributed to the annihilation of positrons from large open space defects. The nature of this defect is discussed. Above 800 K bubble growth is seen
