Abstract
A positron beam with variable energy up to 30 keV has been used to observe defects created by Ne ion implantation in Cu single crystals. The density profile of these defects has a peak centred at a depth much larger than the ion implantation depth; this result is interpreted as being due to dislocation loops formed by aggregation of self-interstitials.Keywords
