U.S.-Brazil Cooperative Research: Experimental and Theoretical Studies of Hyperfine Interactions in Matrix Isolated Systems

该奖项支持由西北大学的Donald Ellis和巴西里约热内卢的Brasileiro de Pesquisas Fisicas(物理研究中心)的E.Baggio-Saitovitch在分子络合物和非晶膜的超精细相互作用方面进行的合作研究。埃利斯对基质隔离系统中超精细相互作用的理论研究将与里约巴乔-赛托维奇实验室正在进行的实验工作密切协调。穆斯堡尔谱学将用于研究原子核中的电荷和自旋分布。将进行超精细参数的实验测定，如同分异构体位移、四极分裂和核磁场。这些研究对化学和材料都很有意义。两国的研究人员都是杰出的、有能力的科学家。主题很重要，理论和实验之间的合作也很重要。当然，巴西队将受益于埃利斯博士的专业知识和西北大学的基础设施。这家巴西集团在基质隔离小粒子化学的穆斯堡尔研究方面做了出色的工作，因此美国集团将从这一经验中受益。

This award supports cooperative research in hyperfine interactions in molecular complexes and amorphous films to be carried out by Donald Ellis at Northwestern University and E. Baggio-Saitovitch at the Centro Brasileiro de Pesquisas Fisicas (Center for Physical Studies) in Rio de Janeiro, Brazil. Theoretical studies of hyperfine interactions in matrix-isolated systems conducted by Ellis will be in close coordination with experimental work going on in the laboratory of Baggio-Saitovitch in Rio. Mossbauer spectroscopy will be used to study charge and spin distributions in nuclei. Experimental determinations will be made of hyperfine parameters such as isomer shift, quadrupole splitting and nuclear magnetic field. These studies are of chemical and materials interest. The investigators in both countries are outstanding and competent scientists. The subject matter is important as is the collaboration between theory and experiment. Certainly the Brazilian team will benefit from the expertise of Dr. Ellis and the Northwestern infrastructure. The Brazilian group has done outstanding work in Mossbauer studies of matrix-isolated, small particle chemistry so the U.S. group will benefit from this experience.
