RUI: Ultrasonic Studies in the Alkali Metals

他们的计划将包括四个主题。 (1)直接 超声波在碱金属中的电磁产生。 这 包括寻找晶格不稳定性，电荷密度波 (CDW)结构和高磁场中的测量。 （二） 碱金属中单晶生长和中子衍射研究 金属，与橡树岭国家大学的人合作， 实验室，密苏里州大学，和国家研究所 标准和技术。 他们将研究钠，锂， 锂镁合金 (3)超声衰减和 高温超导体中的速度， 自己的样品。 他们将研究各种样品， 包括压力效应。 (4)超声波研究附近的 碱金属（钠、钾、铯）的熔点。 他们 希望能达到熔点0.1 mK以内。

Their program will consist of four topics. (1) Direct electromagnetic generation of ultrasound in alkali metals. This includes looking for lattice instabilities, charge-density wave (CDW) structure, and measurements in high magnetic fields. (2) Single crystal growth and neutron diffraction studies in alkali metals, in collaboration with people at Oak Ridge National Laboratory, University of Missouri, and National Institute of Standards and Technology. They will look at sodium, lithium, and lithium magnesium alloys. (3) Ultrasonic attenuation and velocity in high temperature superconductors using primarily their own samples. They will look at a variety of samples and include pressure effects. (4) Ultrasonic studies near the melting point in alkali metals (sodium, potassium, cesium). They hope to reach within 0.1 mK of melting point.
