High Resolution Laser Spectroscopy, Visit to Develop a JointResearch Project, Travel Award in Indian Currency

技术说明：这是一个旅行奖项，旨在最终敲定高分辨率激光光谱学领域的研究提案，该提案将提交给美国国家科学基金会。阿德尔菲大学的拉奥博士将与坎普尔印度理工学院的斯里瓦斯塔瓦博士敲定一项合作研究提案。拟开展的研究是高分辨率无多普勒激光光谱学。这使得研究超窄的原子/分子线形、线宽和微小的能量移动成为可能。许多正常情况下无法观测到的新物理现象现在可以测量到。利用高分辨率的无多普勒激光光谱技术提供的高精度和极高的灵敏度，将被用来研究1)原子能级的超精细结构，包括里德堡态和电子-离子碰撞中原子和分子的激发和自电离；2)原子的超精细结构和原子的非线性极化；速率系数、碰撞电子激发转移和其他原子和分子参数。范围：这项提议是为了支持Rao博士前往印度坎普尔，他应印度物理系的邀请，领导开发一个合作计划，以利用他们高分辨率激光光谱分析实验室的尖端设施。这是印度唯一的此类实验室，已被科技部确定为高度感兴趣的领域。拉奥博士与坎普尔的几位科学家合作，希望提供必要的专业知识来启动该项目。

Technical Narrative: This is a travel award to finalize a research proposal in the area of high resolution laser spectroscopy which will be submitted to the NSF. Dr. Rao of Adelphi University will finalize a collaborative research proposal with Dr. Srivastava of the Indian Institute of Technology, Kanpur. The proposed research is high resolution doppler free laser spectroscopy. This enables the study of ultra narrow atomic/molecular lineshapes, linewidths and small energy shifts. Many new physical phenomena which are not normally accessible can be measured now. High precision and extreme sensitivity offered by the high resolution Doppler free laser spectroscopy techniques will be employed to study 1) the hyperfine structure of the atomic levels including Rydberg states and the excitation and autoionization of atoms and molecules in electron-ion collisions 2) atomic hyperfine structure and the nonlinear polarization of the atoms using Degenerate Four Wave Mixing 3) of collision cross sections, rate coefficients, collisional electronic excitation transfer and other atomic and molecular parameters. Scope: This proposal is to support Dr. Rao's travel to Kanpur, India where he has been invited by the Department of Physics, Head to develop a collaborative program to utilize the sophisticated facilities at their high resolution laser spectroscopy laboratory. This is the only laboratory of its kind in India and has been identified by the Department of Science and Technology as a high interest area. Dr. Rao in collaboration with several scientists at Kanpur expects to provide the necessary expertise to initiate the project.
