U.S.-India Collaborative Research: Elastic Scattering and Pair Production of 1.115 MeV Photons

描述：这是一个美印合作研究项目，名为1.115 MeV光子的弹性散射和对产生。该项目由匹兹堡大学的Richard H. Pratt和大吉岭北孟加拉大学的S.K. Sen Gupta指导。同时，对光子原子散射和通过色散关系产生对的相关过程进行理论和实验上的合作研究。该项目将关注德尔布吕克散射和原子筛查对生产的影响。期望新的理论计算和新的精确实验数据的结合将提高我们对这些重要的光子原子相互作用过程的认识。范围：此次合作是先前资助的INT/India项目活动的结果。关于高能光子与物质相互作用研究新方向的讲习班于1995年11月在大吉岭举行。虽然讲习班的主题是一个现代领域，但两国物理学研究的悠久传统构成了发展正在进行的合作活动的坚实基础。除了研究的直接科学效益外，该合作还将促进思想交流，为学生提供培训，并促进他们接触国际科学界。＊＊＊

9631330 Pratt Description: This is a U.S.-India research collaboration entitled Elastic Scattering and Pair Production of 1.115 MeV Photons. The project is under the direction of Richard H. Pratt, University of Pittsburgh and S.K. Sen Gupta, North Bengal University, Darjeeling. Simultaneous cooperative investigations, both theoretical and experimental, are proposed on aspects of the related processes of photon atom scattering and pair production, connected through dispersion relations. The project will focus on Delbruck scattering and on atomic screening effects in pair production. It is expected that the combination of new theoretical calculations and new accurate experimental data will improve our understanding of these important photon atom interaction processes. Scope: This collaboration is an outgrowth of a previously funded INT/India Program activity. The workshop on New Directions in the Study of the Interaction of Energetic Photons with Matter was held in Darjeeling in November 1995. While the subject matter of the workshop is a modern field, the long tradition of physics research in both countries constitutes a strong basis for developing ongoing cooperative activities. In addition to the immediate scientific benefit of the research, the collaboration will promote the exchange of ideas, provide training of students, and foster their exposure to the international scientific community. ***
