This value for the polarizability is different from that given in ref. [7]. We do not understand how the value cited there was obtained.

It is very confusing to make detailed comparisons with the published thermodynamic data. In ref. [6], figs. 4 and 7 are inconsistent with one another: the pressure-temperature points for half coverage on the phase diagram, fig. 7, are not those read from the isobars using the legend in fig. 4. This inconsistency remains even if it is assumed the gauge correction was neglected in the legend in fig. 4. In Palmberg's experiments the reported temperatures are all considerably higher for a given coverage and pressure than in either ref. [6] or in this work. In fact, from the phase diagrams of either this work or ref. [6], a full monolayer could not have been formed at the highest pressure and lowest temperature reached in Palmberg's experiments. An alternative explanation of the behavior in his fig. 2 where the Auger signal stops increasing with continued exposure is that the equilibrium coverage has been reached for the pressure and temperature of the experiment.

st with Xe coverage is explained by permanent dipole repulsions., This is contrary to Bruch's calculations. Their analysis is based on the old suggestion that the adatoms are polarized in some surface field outside the metal. Lang [46] has shown with a fully self-consistent and quantum mechanical calculation that the polarization of the adatom by the electrostatic field is a much smaller effect than the interaction of the valence electron with its exchange correlation hole which favors the electron being on the metal side of the atom. Thus the Miranda analysis is not correct, but even if it were it does not give an interaction that would fill the attractive well due to the dispersion forces which must be present. This attractive interaction is ignored in their analysis.
