title: Condensation of 3He and reentrant superfluidity in submonolayer 3He- 4He mixture films on H2.
abstract: We have studied the effect of 3He on the superfluid response of submonolayer 4He films adsorbed on H2. In a limited range of 4He coverage, the introduction of 3He brings forth sequentially the normal, superfluid, and the normal phase again. This novel behavior is very likely the consequence of the condensation of the 3He atoms confined near the free surface of the superfluid 4He film into a self-bound 2D liquid.
