This three-year award supports ongoing U.S.-U.K. research collaboration in neutron scattering studies of quantum liquids between Paul Sokol of Pennsylvania State University and W. G. Stirling of the University of Keele. The objective of their research is to conduct neutron scattering studies of microscopic statics and dynamics of quantum liquids and solids in a variety of different environments. Energy inelastic, quasi-elastic and elastic neutron scattering techniques will be applied to quantum liquids and solids, particularly liquid helium. The U.S. investigator brings to this collaboration expertise in high energy neutron scattering, spallation sources, and numerical simulations of instrumental resolution. This is complemented by the British investigator's experience in the measurement of collective excitations and with instruments at reactor sources. Measurements will be carried out at neutron scattering facilities in the U.S. and Europe, including the ISIS Spallation Source at Rutherford Appleton Laboratory in the United Kingdom and the Institut Laue Langevin in France.

这个为期三年的奖项支持宾夕法尼亚州立大学的 Paul Sokol 和基尔大学的 W. G. Stirling 之间正在进行的美英量子液体中子散射研究合作。 他们研究的目的是对各种不同环境中量子液体和固体的微观静力学和动力学进行中子散射研究。 能量非弹性、准弹性和弹性中子散射技术将应用于量子液体和固体，特别是液氦。 美国研究人员为此次合作带来了高能中子散射、散裂源和仪器分辨率数值模拟方面的专业知识。 英国调查员在集体激发测量和反应堆源仪器方面的经验补充了这一点。 测量将在美国和欧洲的中子散射设施进行，包括英国卢瑟福阿普尔顿实验室的 ISIS 散裂源和法国劳厄朗之万研究所。
