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，用于完成高分辨率激光光谱学领域的研究计划，该计划将提交给美国国家科学基金会。阿德菲大学的拉奥博士将与印度理工学院坎普尔分校的斯里瓦斯塔瓦博士完成一项合作研究计划。提出的研究是高分辨率多普勒自由激光光谱学。这使得研究超窄的原子/分子线形、线宽和小能量位移成为可能。许多通常无法接近的新物理现象现在可以测量。高分辨率多普勒自由激光光谱技术提供的高精度和极高灵敏度将用于研究1)原子能级的超精细结构，包括里德伯态和电子-离子碰撞中原子和分子的激发和自离化2)原子超精细结构和原子的非线性极化碰撞截面、速率系数、碰撞电子激发传递等原子分子参数的四波混频。范围：本提案是为了支持Rao博士前往印度坎普尔的旅行，他应物理系主任的邀请，在那里开发一个合作项目，利用他们高分辨率激光光谱实验室的先进设备。这是印度唯一的同类实验室，并已被科技部确定为高兴趣领域。饶博士与坎普尔的几位科学家合作，希望为启动该项目提供必要的专业知识。

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.
