The mechanism of blister formation on a cold-rolled gold target by 3.52 MeV helium ion bombardment was investigated. The critical dose was found to be 6 × 1017 He+/cm2 under the experimental condition used. To study the inner morphology of the blisters, they were opened mechanically. Based on these observations several new features are reported. A speculative model of high-energy blister formation is discussed, based on the fact that the diameter increases in discontinuous steps. It is pointed out that in MeV energy region this formation could be exfoliation rather than blistering confirming the previous investigations.
