[en] Energetic displacement cascades were studied in Ag and Au in the temperature range 10 to 573 K. The cascades were produced by self ion bombardment between 200 and 600 keV. The damage rates are estimated from electrical resistivity (ER) measurements and from transmission electron microscopy (TEM) observations. The splitting into subcascades is quite pronounced in this energy range and is seen by TEM over the whole range (300 to 573 K) of observation. Above state III, damage rates are 1/3 or more of those near 10 K as measured by ER changes. These measurements, together with TEM data on depleted zone clusters, present strong evidence for a very effective separation of interstitials and vacancies in the cascade generation process. It is evident that at elevated temperatures a considerable number of defects survive in the form of defect clusters
