Smedskjaer, L C

The prevacancy effects sometimes observed in high-purity, well-annealed metals, are discussed. It is concluded that these effects are extrinsic and are most likely due to positron trapping in defects. The nature of the defects is discussed, and it is pointed out that the presence of dislocations in the samples could cause prevacancy effects.
