      abstract     = {We report x-ray photoelectron spectroscopy (XPS) study of
                      Na and K adlayers on icosahedral Al70.5Pd21Mn8.5
                      (i-Al-Pd-Mn) quasicrystal. The Na 1s core-level exhibits a
                      continuous linear shift of 0.8 eV towards lower binding
                      energies (BE) with increasing coverage up to one monolayer
                      (ML) saturation coverage. In the case of K/i-Al-Pd-Mn, a
                      similar linear shift in the K 2p spectra towards lower BE is
                      observed. In both cases, the plasmon related loss features
                      are observed only above 1 ML. The substrate core-level
                      peaks, such as Al 2p, do not exhibit any shift with the
                      adlayer deposition up to the highest coverage. Based on
                      these experimental observations and previous studies of
                      alkali metal growth on metals, we conclude that below 1 ML,
                      both Na and K form a dispersed phase on i-Al-Pd-Mn and there
                      is hardly any charge transfer to the substrate. The
                      variation of the adlayer and substrate core-level
                      intensities with coverage indicates layer by layer growth.},
