摘要：

Wetting properties of alkali-metallic surfaces by superfluid-helium film have been tested through heat transport. Appearing as an exception among other substrates, cesium is found to interrupt superfluid-film flow, suggesting nonwetting of cesium by superfluid helium. In addition, superfluid-helium films were observed to be only marginally stable on glass having been in contact with cesium vapor.
