Abstract : Described is a search for hot atom beam sources, primarily halogen and hydrogen sources, for the energy range from 0.1 to 100 electron volts. It was shown for the first time that cathode sputtering of non-metals is feasible and results in formation of neutral species. Also investigated were the hot atom reactions of alkali metals with diatomic molecules as scattering targets. It was shown that the inelastic energy loss of potassium and cesium atoms in collisions with diatomics (chlorine, bromine, and oxygen) is relatively large and surprisingly constant (6-8 eV), quite independent of incident energy of the alkali metal.
