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...
