我们报告的第一次测量的超流密度薄{sup 3}He膜的厚度范围很广。与以前的实验相比，我们发现很好的协议与一般理论的超流转变温度{italT}{sub {italc}}的抑制的预测。此外，我们发现了一个新的阶段的超流体薄膜薄于2750埃的证据。
We report the first measurements of the superfluid density of thin {sup 3}He films for a broad range of thicknesses. In contrast to previous experiments, we find good agreement with the predictions of the general theory for the suppression of the superfluid transition temperature {ital T}{sub {ital c}}. In addition, we find evidence for a new phase of the superfluid in films thinner than 2750 A.
