| Abstract: | Heat transfer between normal liquid 3He and sintered powders is investigated in terms of the Landau Fermi liquid theory. It is shown that the coupling between zero sound in 3He and low energy vibrational modes in sinter gives the extra contribution to the heat transfer below about 10mK. Theoretical results are compared with experimental data from 2mK to 100mK. |
