Sputtering Yields for Low Energy He+-, Kr+-, and Xe+-Ion Bombardment

Abstract
Sputtering yields of various metals have been determined for He+‐, Kr+‐, and Xe+‐ion bombardment in the energy range 100 to 600 ev. Yields at 400 ev show a periodic dependence on atomic number similar to that of the reciprocals of the heats of sublimation.
