Finite size effects in adsorption of helium mixtures by alkali substrates
We investigate the behavior of mixed 3He-4He droplets on alkali surfaces at zero temperature, within the frame of Finite Range Density Functional theory. The properties of one single 3He atom on 4HeN4 droplets on different alkali surfaces are addressed, and the energetics and structure of 4HeN4 + 3H...

Sumario: | We investigate the behavior of mixed 3He-4He droplets on alkali surfaces at zero temperature, within the frame of Finite Range Density Functional theory. The properties of one single 3He atom on 4HeN4 droplets on different alkali surfaces are addressed, and the energetics and structure of 4HeN4 + 3HeN3 systems on Cs surfaces, for nanoscopic 4He drops, are analyzed through the solutions of the mean field equations for varying number N3 of 3He atoms. We discuss the size effects on the single particle spectrum of 3He atoms and on the shapes of both helium distributions. © 2004 Springer Science+Business Media, Inc. |
