    • (unpublished). Some pecularities of the Hg surface structure may be due to the fact that Hg cannot be studied under ultrahigh vacuum (UHV). In the present paper, we compare the In results to measurements of liquid Ga, both performed under UHV conditions. A detailed discussion of the temperature dependent surface layering of liquid Hg will be given elsewhere

    • X-ray photoelectron spectroscopy (XPS) shows that no impurity segregates at the surface of liquid In contained in a Mo pan. The sample was heated up to (Formula presented) for several days and the XPS was taken after cooling the sample. The surface sensitivity of the XPS spectrometer is 1% given a penetration depth of about 30 Å. This is in accordance with the In-Mo phase diagram which predicts no Mo solubility in In at these temperatures [T. B. Massalski, Binary Alloy Phase Diagram (ASM International, Materials Park, OH, 1990)].

    • This cutoff is selected such that the number of capillary modes is equal to the number of surface atoms. Choice of a larger cutoff length would imply that the local density profile includes contributions from averaging over the capillary waves with the shortest wavelengths. First principle arguments that might support such a larger cutoff length are beyond the scope of this paper. A smaller cutoff length on the other hand would imply capillary waves with wavelengths smaller than the particle size which is not physically reasonable.
