Abstract
Singly charged, positive and negative, atomic ions have been observed to sublime freely from 4d and 5d transition metal surfaces in the 1800 to 2600 K temperature range. The rates of sublimation were found to be about equal to those which would be observed under conditions of thermal equilibrium. Ion sublimation energies were obtained from the temperature dependence of these sublimation rates. The energies were found to be consistent with currently accepted values for the atom sublimation energy, electron work function, and first ionization potentials of the elements investigated.Keywords
