Migration and agglomeration of helium atoms in copper

  • 1. Konstanz Univ. (Germany, F.R.). Fakultaet fuer Physik

Description

The migration and agglomeration of helium atoms in He irradiated Cu was studied between 10 K and 900 K by perturbed γγ angular correlation (PAC) measurements using the radioactive probe atom 111In. Trapping of interstitial and substitutional He atoms is observed already after irradiation at 10 K. Substitutional He (He-vacancy pair) is bound in the nearest neighbourhood to the 111In probe atom and seems to be stable up to 725 K (EbHe1V1 ≥ 2.1 eV). The onset of vacancy assisted He agglomeration in Cu is observed at 250 K. (orig.)
