摘要：

An experiment on temperature pulse propagation in a bcc crystal of He3 grown at 95.9 atm shows the existence of second sound in the solid below about 0.58°K. In the temperature range 0.42°K<T<0.58°K, reflections of the received pulses were observed. In the range 0.58°K<T<1.2°K, the temperature pulses were observed to propagate diffusively. © 1969 The American Physical Society.
