“…Changes in silver surfaces in the presence of gases and vacuum have been discussed by others. [10][11][12][13][14][15][16][17][18][19][20] It is obviously impossible to deduce the structure of the new surface generated by OAOR cycling with the certainty of direct techniques such as field emission, low energy electron diffraction, and electron microscopy. However, it does not seem implausible to conclude that the adsorbed oxygen atom ions order the silver atoms into small stable arrays or facets in the chemisorptive rearrangement process.…”
