小行星9726767 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。 研究人员将进行与高密度低温气体激光光泵浦新应用有关的研究。 本研究的目的是：（1）对低温超流氦池中的光抽运特性进行全面细致的研究。（2）在超流He膜池中建立了测量Cs原子电偶极矩的实验。 该项目汇集了两个实验室的努力，这两个实验室具有互补的专业知识、研究能力和设备。 这项合作将把普林斯顿大学在激光泵浦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。 日本合作者是低温电池中碱金属蒸汽操作的世界领导者。 这项研究应该提供洞察力的有效性，目前的理论模型的光泵浦，并可能有助于改善目前存在的理论和实验之间的一些分歧。 通过交流思想和技术，该项目将扩大我们的基础知识，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.
