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威尔金斯这个为期三年的奖项支持美国和法国在凝聚态物理方面的合作研究，该研究由俄亥俄州立大学的John W.Wilkins、俄亥俄州立大学的Mebark Alouani和南希大学的Christian Brouder(法国电磁射线应用实验室)共同完成。他们的研究目的是利用圆磁x射线二向色性(CMXD)研究导致过渡金属和稀土化合物磁性有序的长程相互作用。CMXD是一种新的光谱学，具有提供大范围磁性体系的磁性信息的潜力。所提出的理论方法和计算方法的研究将推动CMXD技术和发展。美国调查人员将理论专业知识和他们的新数字代码带到了这次合作中。此外，法国研究小组将多重散射理论应用于这些问题，并在诱饵实验室建立了出色的实验设备。
