摘要：

We present evidence from UPS measurements that the 4s-induced resonance of K on Ag(100) at low coverages is located well above the Fermi level and at ~ 0.5 monolayer suddenly drops to a position at the Fermi level; i.e. the ionic-to-neutral transition is abrupt rather than gradual. This transition is also correlated with a change in work function. © 1990.
