Sputtering of solid deuterium by bombardment of He-3(+) and He-4(+) ions wa
s studied. Some features are similar to hydrogen ion bombardment of solid d
euterium, but for the He-ions a significant contribution of elastic process
es to the total Yield can be identified. The thin-film enhancement is more
pronounced than that for hydrogen projectiles in the same energy range. (C)
