We have developed a new technique to study superfluidity in saturated liquid /sup 3/He films. Using the enhanced sensitivity of this new method, we directly observe the suppression of the film's transition temperature T/sub c//sup f/ as the film thickness decreases. We also measure a well defined maximum critical film current which scales with temperature as (1-T/T/sub c//sup f/)/sup a/, where a = 1.5 +- 0.17.
