9314455 Wilkins This three-year award supports U.S.-France cooperative research in condensed matter physics between John W. Wilkins, Mebarek Alouani of Ohio State University and Christian Brouder of the University of Nancy and LURE (the French Laboratory for the Application of Electromagnetic Rays). The objective of their research is to study the long-range interaction that causes magnetic ordering in transition-metals and rare-earth compounds by using circular magnetic x-ray dichroism (CMXD). CMXD is a new spectroscopy with potential of providing information of the magnetic properties of a broad range of magnetic systems. The proposed research on a theoretical approach and calculations will advance CMXD technique and development. The U.S. investigators bring to this collaboration theoretical expertise and their new numerical codes. This is complemented by French group's adaptation of multiple-scattering theory to these problems and the excellent experimental facilities at LURE.

9314455 Wilkins 这项为期三年的奖项支持俄亥俄州立大学的 John W. Wilkins、Mebarek Alouani 以及南希大学和 LURE（法国电磁射线应用实验室）的 Christian Brouder 之间在凝聚态物理方面的美法合作研究。 他们研究的目的是利用圆磁 X 射线二色性 (CMXD) 研究引起过渡金属和稀土化合物磁有序的长程相互作用。 CMXD 是一种新的光谱学，具有提供各种磁系统磁特性信息的潜力。 所提出的理论方法和计算研究将推动 CMXD 技术和发展。 美国研究人员为此次合作带来了理论专业知识和新的数字代码。 法国研究小组针对这些问题采用的多重散射理论以及 LURE 优良的实验设施补充了这一点。
