原位形变固体~ 3 He中无序（玻璃）相的研究
A search for disordered (glassy) phase in solid 3He deformed in situ
摘要：
在实验过程中，采用精确的压力测量，在固体3 He中发现了一种无序（玻璃态）。在恒定体积下测量的晶体压力的温度依赖性的分析表明，主要贡献的压力是由声子子系统，无序相的影响是非常微弱的。变形晶体的退火不影响这种状态。所获得的结果有很大的不同，从相应的数据为固体4 He测量的超固体效应的区域中的压力过大的声子相比，登记。超压与温度成二次关系，这是典型的无序系统。固体3 He中是否存在超压尚不清楚，提出了一些推测性的解释。
英文摘要：
A disordered (glassy) state has been searched in solid 3He deformed in the course of experiment employing precise measurements of pressure. The analysis of the temperature dependence of the crystal pressure measured at a constant volume shows that the main contribution to the pressure is made by the phonon subsystem, the influence of the disordered phase being very weak. Annealing of the deformed crystal does not affect this state. The results obtained differ greatly from the corresponding data for solid 4He measured in the region of supersolid effects where a pressure excessive in comparison to the phonon one was registered. The excess pressure had a quadratic dependence on temperature, which is typical of a disordered system. Absence of the excess pressure in solid 3He is unclear yet, some speculative interpretations are suggested.
