项目摘要

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. ***

9631330 Pratt说明：这是美国印度研究的合作，标题为1.115 MeV光子的弹性散射和配对的生产。该项目位于理查德·普拉特（Richard H. Pratt），匹兹堡大学和S.K.的指导下。大吉岭北孟加拉大学森古普塔。理论和实验性的同时合作研究是针对通过分散关系连接的光子原子散射和配对生产的相关过程的各个方面的。该项目将重点放在配对生产中的Delbruck散射和原子筛选效果上。预计新的理论计算和新的准确实验数据的组合将提高我们对这些重要的光子原子相互作用过程的理解。范围：这种合作是先前资助的国际/印度计划活动的产物。 1995年11月，在大吉岭举行了有关能量光子与物质相互作用的新方向的研讨会。虽然研讨会的主题是一个现代领域，但两国的物理研究的悠久传统构成了强大的基础，这是一个强大的基础。开展正在进行的合作活动。除了研究的直接科学利益外，该协作还将促进思想的交流，提供学生的培训并促进他们对国际科学界的接触。 ***
