The (110) and (111) planes of monocrystalline nickel targets have been bombarded with 500-keV /sup 4/He/sup +/ ions under channeling conditions for a total dose of 6 x 10/sup 18/ ions/cm/sup 2/ and for target temperatures ranging from room temperature to 950 /sup 0/C. The results indicate a decrease in average blister diameter with increase in target temperature. Large-scale exfoliation of blister skin occurs at 300 /sup 0/C, and, above 850 /sup 0/C, holes are observed on the surface.
