固体~ 4 He的质量输运观测

Observation of Mass Transport through Solid 4He

M. W. Ray, R. B. Hallock

摘要:

通过使用一种新的实验设计,一个提供的超流氦接触散装hcp 4 He的熔化曲线,我们已经观察到直流传输的质量通过一个充满固体4 He在hcp区域的相图的细胞。流动,表现出超流的特征,被认为是独立的方法来生长固体,但取决于压力和温度。温度依赖性表明滞后的可能性。

英文摘要:

By use of a novel experimental design, one that provides for superfluid helium in contact with bulk hcp 4He off the melting curve, we have observed the DC transport of mass through a cell filled with solid 4He in the hcp region of the phase diagram. Flow, which shows characteristics of a superflow, is seen to be independent of the method used to grow the solid, but depends on pressure and temperature. The temperature dependence suggests the possibility of hysteresis.
