摘要：

The adsorption of water on BaF2(111) and CaF2(111) surfaces has been studied by X-ray photoelectron spectroscopy (XPS). Oxide and hydroxyl species are observed to form reactively on both surfaces with low sticking probability. XPS results imply an exchange of oxygen for fluorine at the surface. There is no evidence for molecularly adsorbed H2O species at 300 K with exposures up to 107 langmuirs in vacuum on either surface.
