• A study has been made on the surface of polycrystalline molybdenum bombarded with H_2^+ or He^+ at energies of 15-40 keV at dose rates of 0.6-2.1 mA/cm^2 to doses below 38 C/cm^2 at temperatures of 250-830℃.The results show that there is no qualitative differnce between the erosion properties of H_2^+ and He^+, but that the erosion yields of He^+ are about an order of magnitude larger than those of H_2^+.At relatively high dose rates, erosion enhancement occurs, with yields several times as large as sputtering yields.This enhancement is usually suppressed to some extent because of the surface roughness formed in the erosion process.The properties and the mechanisms of these phenomena are discussed.
