Description

The release of gas from a metal target during monoenergetic He implantation has been found to be closely correlated to blister formation in Ni. However, in earlier work on Nb and Mo preblister reemission was postulated. In the present work the surface topography of Nb is investigated close to the onset of reemission which could be determined exactly by reemission spectroscopy. Blister formation was found immediately after the start of gas reemission, suggesting a similar mechanism for reemission as in Ni. The influence of target pretreatment is also described. (orig.)
