摘要：

Thermal-conductivity measurements in solid He3 in the bcc phase and at temperatures below about 0.5°K show an unexpected temperature dependence which is less than T3. Specific-heat measurements, in this temperature range, have been reported as showing a closely similar effect, and this provides evidence for a thermal excitation which must take part in the heat transport. In addition, Poiseuille flow of phonons has been directly observed. © 1969 The American Physical Society.
