摘要：

Electron emission spectra observed on collisionally excited sodium halide surfaces indicate that the sodium deexcitation process in ionic solids is more complex than that in metallic sodium. The spectra for the sodium halides can be interpreted in the context of a collisional deexcitation model in which the charge state of the excited sodium determines the deexcitation process. Electron capture, which can only occur when an excited sodium ion collides with a static lattice ion, dominates this deexcitation process and is direCtly responsible for the observed spectra.
