The interaction of cascades at higher doses was found to produce new clusters near existing groups of vacancy clusters, apparently converting invisible vacancy-rich regions to visible vacancy clusters.

In thin gold foil, at lower bombardment doses, the interactions of cascades are insignificant, and both visible vacancy clusters and invisible vacancy-rich regions are formed by cascade collision sequences.
