Photoemission studies of single-crystalline samples of Bi{sub 2}Sr{sub 2}CuO{sub 6} show clear resemblance to the corresponding data for single crystals of Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8}. In particular, a sharp Fermi-level cutoff, giving evidence of metallic conductivity at room temperature, as well as single-component O 1{ital s} emission and Cu 2{ital p} satellites with a strength amounting to about 50% of that of the main Cu 2{ital p} line, are observed. An analysis of the relative core-level photoemission intensities shows that the preferential cleavage plane of single-crystalline Bi{sub 2}Sr{sub 2}CuO{sub 6} is between adjacent Bi-O layers. Deposition of Ag adatoms causes only weak reaction with the Bi and O ions of the Bi{sub 2}Sr{sub 2}CuO{sub 6} substrate, while the Cu states rapidly react with the Ag adatoms, as monitored by a continuous reduction of the Cu 2{ital p} satellite intensity as the Ag overlayer becomes thicker.
