9726767 Happer该奖项支持普林斯顿大学的William Happer教授和日本京都大学的Tsutomu Yabuzaki教授之间为期三年的合作研究项目。研究人员将开展与激光光学泵浦高密度低温气体的新应用相关的研究。本研究的目标是：(1)对超流He包覆的低温池中的光泵浦光进行详细的表征。(2)发展了一种测量Cs原子在超流He涂层电池中的电偶极矩(EDM)的实验。该项目汇集了两个拥有互补专业知识、研究能力和设备的实验室的努力。这项合作将把普林斯顿大学在激光光泵和自旋交换方面的实验和理论专业知识与京都大学开发的低温技术结合起来。这位日本合作者在处理低温电池中的碱金属蒸气方面处于世界领先地位。这项研究应该有助于洞察当前光抽运理论模型的有效性，并可能有助于改善目前存在的一些理论和实验之间的分歧。通过思想和技术的交流，这个项目将扩大我们的基础知识基础，促进国际理解与合作。

9726767 Happer This award supports a three year collaborative research project between Professor William Happer of Princeton University and Professor Tsutomu Yabuzaki of Kyoto University in Japan. The researchers will be undertaking studies relating to new applications for laser optical pumping of high density, low temperature gases. The objectives of the research are: (1) to undertake a complete detailed characterization of optical pumping in low temperature cells, coated with superfluid He. and (2) to develop an experiment to measure the electric dipole moment (EDM) of atomic Cs in a superfluid He coated cell. This project brings together the efforts of two laboratories that have complementary expertise, research capabilities and equipment. The collaboration will unite the experimental and theoretical expertise in laser optical pumping and spin exchange at Princeton with the cryogenic techniques developed at Kyoto University. The Japanese collaborator is a world leader in the manipulation of alkali metal vapors in cryogenic cells. The research should provide insight into the validity of current theoretical models of optical pumping and possibly help ameliorate some of the disagreements between theory and experiments that currently exist. Through the exchange of ideas and technology, this project will broaden our base of basic knowledge and promote international understanding and cooperation.
