This action funds Renata Cumbee of the University of Georgia to conduct a research project in the Mathematical and Physical Sciences area during the summer of 2013 at the College of Material Sciences and Optoelectronic Technology at the University of the Chinese Academy of Sciences in Beijing, China. The project title is "Highly-Charged Ion Collisions with Atoms: Applications to X-ray Emission in the Solar System." The host scientist is Prof. Yizhi Qu.To improve the quality of current x-ray models in astrophysics, this project uses explicit quantum-mechanical cross section calculations produced by Prof. Qu's group for the collisional process of charge exchange for important solar wind ions and velocities colliding with heliospheric neutral atoms which enables detailed spectral modeling needed to exploit current X-ray observations. The project performs the calculations for the important collision systems of important solar wind ions Ne9+ and Mg11+ colliding with neutral H. The calculations are performed over the relevant collision energies, 10 eV/u to 50 keV/u, and include state selective cross sections to all important n, l, S-resolved states. In particular, this work focuses on the resulting nonequilibrium distributions created in the quantum-resolved n, l, S states. This project will have a direct impact on advancing our understanding of atomic collisions and the solar wind interaction with the heliosphere.Broader impacts of an EAPSI fellowship include providing the Fellow a first-hand research experience outside the U.S.; an introduction to the science, science policy, and scientific infrastructure of the respective location; and an orientation to the society, culture and language. These activities meet the NSF goal to educate for international collaborations early in the career of its scientists, engineers, and educators, thus ensuring a globally aware U.S. scientific workforce. Furthermore, when the EAPSI fellowship is complete, the Fellow will have the opportunity to train other graduate students in her field of research and through seminars, she will be able to recruit students to apply to this fellowship in future years.

该行动资助格鲁吉亚大学的Renata Cumbee于2013年夏季在中国北京中国科学院大学材料科学与光电技术学院开展数学和物理科学领域的研究项目。 该项目的名称是“高电荷离子与原子的碰撞：在太阳系X射线发射中的应用”。“主持科学家为曲毅智教授。为了改善目前天体物理学中X射线模型的质量，本项目使用曲教授团队的显式量子力学截面计算，计算了重要的太阳风离子与日光层中性原子碰撞的电荷交换过程，从而实现了利用当前X射线观测所需的详细光谱建模。本项目对太阳风中重要离子Ne ~（9+）和Mg ~（11+）与中性H碰撞的重要碰撞系统进行了计算。的计算进行了相关的碰撞能量，10 eV/u至50 keV/u，并包括状态选择性截面的所有重要的n，l，S-分辨状态。特别是，这项工作的重点是在量子分辨的n，l，S状态中产生的非平衡分布。该项目将对促进我们对原子碰撞和太阳风与日光层相互作用的理解产生直接影响。EAPSI研究金的更广泛影响包括为研究员提供美国以外的第一手研究经验;介绍各自所在地的科学，科学政策和科学基础设施;以及社会，文化和语言的方向。 这些活动符合NSF的目标，即在科学家，工程师和教育工作者的职业生涯早期进行国际合作教育，从而确保具有全球意识的美国科学工作者。 此外，当EAPSI研究金完成后，研究员将有机会在她的研究领域培训其他研究生，并通过研讨会，她将能够招募学生在未来几年申请该研究金。
