Abstract
THE peculiar properties of liquid helium II have been the subject of many experimental and theoretical investigations during recent years. The characteristic features of liquid helium II are its superfluidity (viscosity less than one billionth of that of water) and the thermomechanical effect. The superfluidity has been explained by F. London1 and L. Tisza2 by assuming helium II to be in a state of Bose-Einstein degeneracy, a part of the atoms constituting the condensed phase. In a previous communication3, I have given a theory of the surface-flow of liquid helium II in the form of thin mobile films, and my purpose now is to discuss the thermomechanical effect in helium II assuming the latter to be in the state of Bose-Einstein degeneracy.
