Pulsed Magnetic Resonance at Low Temperatures

目的是检查在高密度和低温下吸附物的动力学和相变，并在有限的维度下，使用脉冲核磁共振作为探针。拟开展的研究包括：高密度固体H2、HD和D2的结构、运动、转化和相变研究；Kr和Xe的高压研究；非常详细地研究了H2、HD、D2、Kr和Xe在MgO和BN衬底和多孔介质中的吸附膜；稀光杂质的弛豫及其可能引起的结构跃迁的测量。

The goal is to examine dynamics and phase transitions for adsorbates at high densities and low temperatures, and under restricted dimensionality, using pulsed NMR as a probe. The proposed research includes: studies of structure, motions, conversion and phase-transitions in solid H2, HD and D2 at high densities; high-pressure studies of Kr and Xe; very detailed studies of adsorbed films of H2, HD, D2, Kr and Xe on MgO and BN substrates and in porous media; measurements on the relaxation of dilute light impurities and on the structural transitions they may induce.
