A review of surface effects in Kapitza’s experiments on heat transfer between solids and helium II (Review Article)
In a recent paper, it is shown that the thermal boundary Kapitza resistance between a solid and superfluid helium
 is explained by resonant scattering of phonons from surface roughness heights, as described in the
 Adamenko and Fuks (AF) model. We reexamine the original experiments o...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | In a recent paper, it is shown that the thermal boundary Kapitza resistance between a solid and superfluid helium
is explained by resonant scattering of phonons from surface roughness heights, as described in the
Adamenko and Fuks (AF) model. We reexamine the original experiments of thermal transfer between a solid
(platinum and copper) and superfluid helium conducted by P.L. Kapitza in 1940. In particular, we analyze his
experimental results for the different surface treatments of the solid in light of the AF model. Time scales for diffuse
scattering of phonons at the interface are estimated. Also the role of a layer of varnish on a copper surface is
reinterpreted.
