Notes:
Induced defects in silver polycrystalline samples irradiated with 4 keV Ar+ werecharacterised with slow positron implantation spectroscopy. The implanted gas was found tointeract with ion irradiation defects. The evolution of the defects and gas-defect interactions werefollowed through a multi-step isochronal annealing treatment. Two different defected regions weredetected. A region near to the surface, due to a distribution of vacancy-like defects produced byirradiation, and a deeper one due to coalescence of Ar. The deeper defects evolve with thermaltreatments and probably produce cavities which are not easily recovered
