The (001) faces of a copper single crystal and faces making small angles with the (001) faces were bombarded by 20-keV Ne ions incident at angles from 0/sup 0/ to 11/sup 0/ with respect to the (001) axis in the (110) plane. The dose was 2 x 10/sup 19/ to 1.2 x 10/sup 20/ ions/cm/sup 2/. The resulting surface structure was studied; the number, size, and shape of the etching figures and gas bubbles (blisters) vary rapidly as the angle at which the ions are incident and the angle between the face in question and the (001) face are changed. The greatest number of gas bubbles is observed when the ions are incident along the (001) channel and at an angle of 6 +- 1/sup 0/ from it in the (110) plane. In the latter case the gas bubbles (and the etching figures) are elongated and lie in rows along (110) directions. They reach 80 ..mu.. in length and 6 ..mu.. in width. The number of gas bubbles decreases as the radiation dose is increased from 5 x 10/sup 19/ to 1 x 10/sup 20/ ions/cm/sup 2/. The results are discussed from the standpoint of current ideas regarding the mechanism for the interaction of ions with a solid.
