Abstract

We describe three experiments designed to search for the bound state for3He adjacent to a substrate which has been predicted by Treiner and co-workers. In each case a bulk3He-4He solution is in contact with the substrate of interest. For a Nuclepore substrate, NMR techniques are used to establish that there is no 2D behavior for the3He in the cell; thus, no substrate state is present. For a cesium or hydrogen substrate the technique involves the measurement of the velocity of ordinary sound in the bulk solution as a function of temperature. The cesium and hydrogen experiments are incomplete.
