Former transmission electron microscope (TEM) studies /1,2,3/ on Cu and Au foils, which were bombarded with 1 to 5 keV Ar ions, showed that interstitial clusters (in the configuration of Frank dislocation loops) are formed below the bombarded surface in a depth remarkably larger than the calculated random range of Ar ions. This was interpreted by the propagation of focussing replacement collision sequences (r.c.s.) originating near the end of the heavily damaged layer within the random range of the incoming Ar ions. One of the strongest arguments in support of this interpretation was the dependence of the depth distributions of the interstitial agglomerates on the crystallographic orientation of the foil surface.
