Abstract

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.
