Abstract

Helium wetting and prewetting phenomena at temperatures T>0 are addressed. Emphasis is given to the weak-binding substrates Cs and H2, which have been predicted and observed to be nonwet and wet, respectively, by4He at low temperatures. Calculations of the wetting temperature TW and the prewetting line near TW for Cs, as well as the prewetting line near T=0 for H2, are given. Predictions concerning the interplay between superfluid onset and prewetting are made, and prewetting critical temperatures are estimated.
