Growth of helium shells inside spherical adsorbers

The adsorption of helium on spherical cavities is investigated employing finite range density functional theory. It is known that for films outside spherical walls, a growth instability occurs above a critical film thickness. This instability may be overcome by stable capillary condensation inside t...
