Evaporation from Superfluid Helium

  • Milton W. Cole


Interest in evaporation from liquids arises because the measured variable, the angular and spectral distribution of atoms leaving the liquid surface, may serve as a probe of the properties of a single atom in the liquid. We have found1 for superfluid helium that the liquid—vapor interface plays a mediating role in the microscopic process of evaporation which tends to obscure information about properties of the bulk liquid. However, in so doing, it allows us to obtain information about the surface which is also of intrinsic interest.
