摘要：

We have studied the properties of quasi-two-dimensional 4He in an environment provided by the layered structure of hectorite. A phase transition occurs for areal densities between n=0.029 Å−2 and n=0.032 Å−2 where the structure of 4He changes abruptly from a 4-layer to a 5-layer configuration. The signatures of this phase transition are detectable in the static density–density response function and in the density–dependence of the roton minimum.
