0233203VilesovThis award supports a three-year collaborative research project. The principal investigator for the project is Professor Andrey Vilesov at the University of Southern California. Professor Birgitta Whaley of the University of California in Berkeley will also be participating. The Japanese collaborator is Professor Takamasa Momose at Kyoto University in Japan. They will be undertaking research on the study of quantum hydrogen fluids and crystals. They will combine several experimental and theoretical approaches to study the dynamics of pure and doped hydrogen clusters and crystals. Theoretical calculations will provide detailed insights into the nature of the quantum statistical effects and the effect of the interaction with molecular chromophore core. An important component of the project is the development of the pulsed Raman shifter based on solid para hydrogen crystal, the medium, which is characterized by large gain and extremely narrow lines. This development may give a real break through in the field of pulsed far infrared laser technology (5-10 um), where there are no commercial lasers at present. The project brings together the efforts of three laboratories that have complementary expertise and research capabilities. The U.S. researchers provide expertise of the growth and spectroscopy of pure and molecular doped hydrogen clusters inside ultracold helium droplets and theoretical interpretation of the results, whereas the Japanese group has a unique high resolution (10 MHz) difference frequency generation laser spectrometer and is proficient in infrared spectroscopy (3-10 um) of pure and molecular doped para hydrogen crystals. The collaboration will offer great mutual benefits. The project advances international human resources through the participation of a number of postdocs and graduate students. Through the exchange of ideas and technology, this project will broaden our base of basic knowledge and promote international understanding and cooperation. Results of the research will be disseminated at scientific meetings and in scientific journals.

0233203 Vilesov该奖项支持一个为期三年的合作研究项目。 该项目的首席研究员是南加州大学的安德烈·维列索夫教授。 加州大学伯克利分校的Birgitta Whaley教授也将参加。 日本的合作者是日本京都大学的Takamasa Momose教授。 他们将从事量子氢流体和晶体的研究。 他们将联合收割机几个实验和理论的方法来研究纯和掺杂的氢原子团簇和晶体的动力学。 理论计算将提供详细的洞察的量子统计效应的性质和与分子发色团核心的相互作用的效果。 该项目的一个重要组成部分是基于固体帕拉氢晶体介质的脉冲拉曼移相器的开发，其特点是大增益和极窄的线。 这一发展可能会在脉冲远红外激光技术（5-10 μ m）领域取得真实的突破，目前还没有商用激光器。 该项目汇集了三个具有互补专业知识和研究能力的实验室的努力。 美国研究人员提供了超冷氦滴内纯和分子掺杂氢团簇的生长和光谱学的专业知识以及对结果的理论解释，而日本研究小组拥有独特的高分辨率（10 MHz）差频激光光谱仪，并精通纯和分子掺杂帕拉氢晶体的红外光谱（3-10 um）。 合作将带来巨大的互利。 该项目通过一些博士后和研究生的参与促进国际人力资源。 通过交流思想和技术，该项目将扩大我们的基础知识，促进国际理解与合作。 研究结果将在科学会议和科学期刊上传播。
