Popis:	The nucleation of silver-atom vapor in the presence of O2 and H2O molecules has been investigated by photoionization mass spectrometry and compared to the case of alkali-atom vapor. Relative intensities in mass spectra show that silver vapor does not react with H2O molecules, in contrast with sodium vapor. When O2 and H2O are simultaneously present, hydroxided products are observed. Results emphasize the role of stable units, (NaOH)2 or (KOH)2, for alkalies, and more complex hydrated or hydroxided systems, involving trimers, for silver. Similarities are found with water dissociative adsorption on an oxygen-predosed silver surface.
