Lambert, Colin and Guenault, A. M. and Pickett, G. R. (1986) Depression of the energy gap at a surface in 3He-B; the evidence from thermal boundary conductance. Journal of Physics C: Solid State Physics, 19 (17). L351-L356. ISSN 0022-3719Full text not available from this repository.
A simple expression for the heat flux between sintered silver powder and 3He-B is derived. The heat flux in the superfluid state is expressed in terms of that in the normal state, without the precise mechanism of heat transfer needing to be specified. A comparison with recent measurements suggests that the energy gap involved is a factor of 0.65 of the bulk value. This implies that the gap is depressed near a boundary and that processes occurring close to the boundary dominate the thermal exchange mechanism.
