Abstract：
Measurements of the angular distributions and yields of atoms sputtered from Ag target by bombardment with FeCl⁺,⁵⁶Fe⁺ and ³⁵Cl⁺ are reported.Large enhancement occurs in the measured Ag atom yield for FeCl⁺ projectile in comparison with the sum of the sputtering yields for ⁵⁶Fe⁺ and ³⁵Cl⁺ bombardment at same impact velocities.The enhanecment can be explained by a model of the thermal spike-evaporation plus surface topography effect.
