Abstract: We report the application of a sensitive experimental procedure for the quantitative measurement of population partitions and kinetic energy distributions of metastable atoms ejected during ion-beam-solid interactions. The method, based on double resonant two-colour two-step laser ionization, was applied to study the emission of neutral atoms during 12 keV Ar+ ion-beam sputtering of clean polycrystalline Ni and Co. The combined data provide evidence for resonant electron transfer during the emission process and its dependence on the correspondence of the atomic electronic configuration with the bulk electronic structure.
