Properties of Fluid Helium and of Quantum Solids

第一个研究领域涉及超流转变附近的液氦中的输运性质。提出了1)研究正常相和超流相在热流作用下共存时的非线性温度分布以及界面的动力学。2)继续系统地研究~3He在~4He极稀溶液中的输运性质。第二个领域涉及固体H2和D2中的动力学现象。他们提出：1)通过核磁共振和热导实验，同时通过量子扩散来研究邻位氢原子在氢气中的团簇。2)在一个新的高压室中，将邻位氢团簇的核磁共振测量扩展到1千巴。

The first area of research deals with the transport properties in liquid helium near the superfluid transition. It is proposed 1) to investigate the non-linear temperature profile when the normal and the superfluid phases coexist under a heat current, and the dynamics of the interface. 2) to continue systematic study of transport properties in very dilute solution of 3He in 4He. The second area is concerned with dynamic phenomena in solid H2 and D2. They propose 1) to study the clustering of ortho-H2 in H2 through quantum diffusion simultaneously via NMR and thermal conductivity experiments. 2) to extend in a new high-pressure cell the NMR measurements of ortho-H2 clustering to 1 kilobar.
