Abstract:Abstract. Excited Na* (3 p)-atoms are observed in grazing surface-collision experiments with Na+-beams. Such atoms can be formed beyond a certain threshold velocity via resonant electron transfer between atomic and metallic conduction band levels due to motion of the atom relative to the surface of the metal ("kinematic resonance"). This mechanism is studied here theoretically employing two different techniques: the nonperturbative "Coupled Angular Mode" (CAM) method and the approximate "Transfer Hamiltonian" … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
