The statistical mechanical behavior of quantum gases adsorbed on various surfaces is analyzed. The specific surfaces explored are (a) a finite and an infinite plane, (b) a circular and/or square disk, (c) a sphere, (d) a cylinder, and (e) a cone. The approximation is made that the particles are confined to the close vicinity of the specified surface by a holding potential. As expected, quantum size and statistical effects are large at low temperature, while at high temperature the limiting behavior is that of a classical two-dimensional gas on a flat surface. An application to the surface separation of HD or D 2 from H 2 is discussed.
