TLDR
In situ X-ray photoelectron spectroscopic observation of a silver foil at 473 K exposed to oxygen at pressures up to 0.5 torr has identified three species, characterised by oxygen 1s binding energies of 528.3, 530.3 and 532.5 eV as discussed by the authors.About:

Investigation of solid/vapor interfaces using ambient pressure X-ray photoelectron spectroscopy
TL;DR: This review summarizes the historical development of APXPS since its introduction over forty years ago, discusses different approaches to minimize scattering of electrons by gas molecules, and gives a comprehensive overview about the experimental systems (vapor/solid interfaces) that have been studied so far.

Mechanism of ethylene epoxidation
TL;DR: The mechanism of the epoxidation of ethylene with oxygen over silver catalysts has been examined in this article, where experiments were undertaken to determine whether adsorbed atomic oxygen is incorporated into ethylene to give epoxide, and to establish the relative rates of reaction of molecular oxygen impinging from the gas phase and of preadsorbed atoms.

TL;DR: In this article, the adsorption of oxygen on Ag(110), (111), and (100) surfaces has been investigated by LEED, Auger electron spectroscopy (AES), and by the measurement of work function changes and of kinetics, at and above room temperature and at oxygen pressures up to 10−5Torr.

Surface sensitivity and angular dependence of X-ray photoelectron spectra☆
TL;DR: In this paper, the angular dependence of spectral intensities can be used to differentiate surface from bulk species, and a model is presented to account for the angular dependences and it is proposed that the angular dependencies can be exploited to distinguish surface from other bulk species.
