Abstract = {{We report a room-temperature UV inverse-photoemission study of the early
   oxidation stages of polycrystalline cobalt within the photon energy
   range 12-25 eV for exposures between 1 and 10(4) Langmuir (L) (1 L=
   10(-6)  Torr s). The decomposition of each spectrum related to
   intermediate exposures in terms of bulk Co and oxidized Co, together
   with the analysis of the relative intensities for the different
   contributions, shows the stable formation of CoO at the interface for
   exposures greater-than-or-equal-to 30 L, whereas for lower exposures the
   oxide stoichiometry depends on the amount of oxygen atoms. In the 5-7-L
   range, possible Co3O4 formation takes place consistently with a
   decreased interdiffusion in this regime as compared to the higher
   exposures regime. An estimation of the oxide film thickness at the
   maximum exposure is performed giving a surface oxide thickness of about
   20 angstrom.}},
