Abstract
We present helium metastable-quenching spectra of K/Ni(111) whose spectral features show unusual coverage dependence. These are explained by a mechanism in which the surface ionizes the incident singlet and then neutralizes the ion to form a triplet. These spectra reflect the fact that the local work function varies strongly along the surface.
