US-India Cooperative Research: Investigations on Theoretical Aspects of Compton Scattering

0352483PrattDescription：该奖项支持名为《康普顿散射理论方面的调查》的美印合作研究。匹兹堡大学的理查德·普拉特教授和加尔各答玻色研究所的巴鲁姆·查特吉教授将研究光子与物质相互作用的基本过程之一--非弹性光子(康普顿)散射。这已经成为一个新的研究主题，因为实验测量的精确度已经达到了可以重新检查所有理论计算中固有的基本假设和近似的水平。这项研究通过将最先进的理论计算预测的截面与精确的实验结果以及其他理论预测进行比较，将增加对光子非弹性散射的理论理解的程度。美国国际和平研究所是这一研究领域的国际领先专家。这项合作结合了印度一个实验小组和美国一个理论小组的专业知识，将促进对康普顿散射的基本理解，并激励玻色研究所进行新的实验研究。预计这将加强两国的研究和教育，并鼓励形成新的合作伙伴关系。这项活动由印度政府科学与技术部(DST)根据NSF/DST联合计划共同资助。

Professors Richard Pratt, University of Pittsburgh and Barum Chatterjee, Bose Institute, Calcutta will investigate one of the basic processes by which photons interact with matter, inelastic photon (Compton) scattering. This has become a subject of renewed investigation since the precision of experimental measurements has reached a level at which underlying assumptions and approximations inherent in all theoretical calculations can be reexamined. This research will increase the extent of theoretical understanding of the inelastic scattering of photons, by comparing cross sections predicted from the most advanced theoretical calculations with precise experimental results and with other theoretical predictions. The US PI is the leading international expert in this field of research. The collaboration, which joins the expertise of an experimental group in India with that of a theoretical US group, will advance fundamental understanding of Compton scattering and motivate new experimental studies at the Bose Institute. It is expected to enhance research and education in the both countries and encourage the formation of new partnerships. This activity is cofunded by the Government of India's Department of Science & Technology (DST) under the NSF/DST joint program.
