    • Recently an energy scanned photoelectron diffraction investigation of the K/O-Ni(100) structure has been carried out [P. Finetti, M. J. Scantlebury, M. Sambi, F. Borgatti, and R. McGrath (unpublished)]. The observed absence of modulation of the K (Formula presented) signal again suggests that the K layer is disordered
    • Room temperature coadsorption of K or Cs and O on Ni(100) gives rise to a (3×3) LEED pattern. A strong increase in the LEED background upon coadsorption of Cs on an O precovered surface has been observed and interpreted as due to an AM disordered phase [see C. A. Papageorgopoulos and J. M. Chen, Surf. Sci. 52, 53 (1975)]. Recently an energy scanned photoelectron diffraction investigation of the K/O-Ni(100) structure has been carried out [P. Finetti, M. J. Scantlebury, M. Sambi, F. Borgatti, and R. McGrath (unpublished)]. The observed absence of modulation of the K (Formula presented) signal again suggests that the K layer is disordered.

    • The upward dispersion of the (Formula presented) band in a bidimensional system consisting of an isolated primitive square array of atoms can be predicted, on symmetry grounds, by using a simple tight binding approach. See, for example, A. M. Bradshaw and M. Scheffler, J. Vac. Sci. Technol. 16, 447 (1979).
