Abstract
The oxidation of strontium has been studied by Auger-electron spectroscopy. It is found that the surface of Sr remains metallic during oxidation, in support of recent photoemission experiments. A model based on the large electrostatic or Madelung energy of "ionic" metal/adsorbate systems is suggested that explains the phenomena.Keywords
