Abstract
3He atoms atop a thin film of 4He constitute a conceptually simple but remarkably rich system in which the 3He, depending on the coverage, can be studied from the extremes of a nearly non-interacting 2D Fermi gas, to a 3D interacting liquid. In such a system, the Fermi temperature depends on coverage and, for the 2D case, may he readily tuned. Several important questions may be asked of this system: (1) how does the behavior of the 3He change as the 3He coverage is increased and the interactions among the atoms increase, (2) how does the 3He interact with the 4He film which supports it, (3) for 3He coverages which approach and exceed a monolayer, how does the 3He evolve from a 2D to a 3D system, (4) are there phase transitions in the system as a function of either 3He coverage or temperature, (5) what are the dynamical properties of the 3He as a function of these parameters?

The Ti values from our most recent run represented by figure 6 are generally consistent with earlier runs except for the case of the run whose data is shown in figure 5 where T 1 appears a bit longer. The echo height was the same in the Curie region for the case of d 3 = 0.1 for each of these runs; there is no error in the 3 He coverage. We don’t presently understand this quantitative discrepancy; it does not affect any of the trends of the data within a single run. In all cases in a given run the data are reproducible and heating effects are absent.
