Momentum Distributions and Quantum Liquids

液氦的性质将通过中子- 衍射技术 原子动量分布n（p） 将通过深度非弹性n散射探测，目标为 液态3 He、3 He-4 He混合物和4 He。 在第二项研究中，将使用弹性n散射来探测 多孔介质中氦结构。 特别是，一个将 研究表面随机性在确定 固体的结晶相和玻璃相的结构。

The properties of liquid helium will be studied by neutron- diffraction techniques. The atomic momentum distribution n(p) will be probed by deep inelastic n scattering, for targets of liquid 3He, 3He - 4He mixtures and 4He, in restricted geometries. In a second study, elastic n scattering will be used to probe the helium structure inside porous media. In particular, one will examine the role of the surface randomness in determining the structure of the crystalline and glassy phases of the solid.
