This award provides partial support for a three month research visit by Dr. Wick Haxton of the University of Washington to Australia in order to collaborate with Dr. Bruce H. J. McKellar of Melbourne University. This visit is in exchange for the visit in early 1992 by Prof. McKellar to the University of Washington. Both investigators are acknowledged experts in weak interaction phenomenon, and this visit will extend the collaborative research on several topics in weak interactions. The investigators intend to collaborate on the theory of atomic electric dipole moments with the goal of defining the relationship between measurements and the parameters of the underlying CP (charge/parity) violating Lagrangian. They also intend to consider current treatments of the parity-nonconserving NN (neutron/neutron) interaction in view of recent chiral Lagrangian arguments that S-quark components in the nucleon lead to new interactions, including important three-body nuclear terms.

该奖项为华盛顿大学的 Wick Haxton 博士前往澳大利亚进行为期三个月的研究访问提供部分支持，以便与墨尔本大学的 Bruce H. J. McKellar 博士合作。 此次访问是麦凯勒教授1992年初访问华盛顿大学的交换条件。 两位研究人员都是弱相互作用现象领域公认的专家，此次访问将扩展弱相互作用多个主题的合作研究。 研究人员打算在原子电偶极矩理论方面进行合作，目标是定义测量值与基础 CP（电荷/宇称）破坏拉格朗日参数之间的关系。 鉴于最近的手性拉格朗日论点，即核子中的 S 夸克成分会导致新的相互作用，包括重要的三体核项，他们还打算考虑当前对宇称非守恒 NN（中子/中子）相互作用的处理。
