Elastic and Inelastic Scattering of Gamma Rays, Award in Indian Currency

项目描述：本项目支持美国匹兹堡大学Richard H. Pratt博士与印度孟买印度理工学院P.P. Kane博士之间的合作。主要研究方向是原子对硬x射线和软伽马射线的弹性散射（瑞利散射）和非弹性散射（束缚电子康普顿散射）。重点将放在原子物理学上，它似乎在很大程度上决定了光子-原子散射。拟议的研究还将提供医疗诊断、应用辐射物理和反应堆安全工作人员所需的更准确的数据。目的包括研究弹性散射中的近阈值效应，以及提高对高z原子紧密束缚内壳电子的康普顿散射的理解。工作范围：在光子-原子散射领域进行的高度互补的联合实验和理论研究。美国和印度科学家过去曾在这一领域成功合作研究。这项研究既有基础研究兴趣，也有潜在的应用，有利于两国的科学家和辐射专业人员。对学生的培训是该项目的一个组成部分。该项目得到两项拨款的支持：向匹兹堡大学提供INT 9019385；INT 9102053给孟买的印度理工学院

Description: This project supports cooperation between Dr. Richard H. Pratt of the University of Pittsburgh and Dr. P.P. Kane of the Indian Institute of Technology, Bombay, India. The main research area will be the study of elastic scattering (Rayleigh scattering) and inelastic scattering (bound-electron Compton scattering) of hard x-rays and soft gamma rays by atoms. The focus will be on the atomic physics which appears to largely determine photon-atom scattering. The proposed studies will also provide more accurate data needed by workers in medical diagnostics, applied radiation physics and reactor safety. Objectives include the study of near-threshold effects in elastic scattering, and improved understanding of Compton scattering from tightly-bound inner-shell electrons of high-Z atoms. Scope: The work involves joint experimental and theoretical research between highly-complementary ongoing research programs in photon-atom scattering. The U.S. and Indian scientists have successfully collaborated in research in this area in the past. The research has both basic research interests as well as potential applications that are beneficial to scientists and radiation professionals in the two countries. Training of students is an integral part of the project. The project is being supported under two grants: INT 9019385 to the University of Pittsburgh; INT 9102053 to the Indian Institute of Technology, Bombay
