Connolly, John Irving 2011-05-19T16:16:43Z 2011-05-19T16:16:43Z 10000-01-01 1965 We have measured the thermal conductivity of liquid He3 at low pressure from O. 055 0 K to O. 47 o K, at 99.8 psi from O. 0550 K to O. 750 K and at 396.8 psi from O. 0550 K to O. 87 o K. At all pressures and at sufficiently low temperatures the thermal conductivity increases with decreasing temperature. At low pressures our data agree with the data of Anderson et al* which, at temperatures lower than those investigated in this experiment, agreed with the T- 1 temperature dependence predicted by Fermi liquid theory. At higher pres sures we definitely do not go low enough in temperature for the simple Fermi liquid picture to be valid. At high temperatures the conductivity increases slowly with increasing temperature. Near 10K the effect of pressure on the conductivity, large at lower temperatures, has become very small. At all temperatures the conductivity decreases with increasing pressure. As the pressure is increased the minimum in the conductivity occurs at a lower temperature. These data have provided an experimental basis for theories of transport properties at temperature s too high for the simple Fermi liquid picture to be valid but in a region where degeneracy effects ate still important. The re sults of the se measurements will be published by the author, A. C. Anderson, O. E. Vilches, and J. C. Wheatley.
