0138115曼森描述：该奖项支持美国和印度的合作，题为自由和受限原子光电离中的相对论效应。 美国PI Steven曼森，格鲁吉亚州立大学（GSU）和Pranawa Deshmukh，印度理工学院（IIT），马德拉斯将继续开发理论方法，并进行计算，探索电磁辐射与原子和离子的电离碰撞。 他们将开发相对论随机相位近似（RRPA）方法，并将其应用于电磁辐射电离自由和受限原子和离子领域的许多不同问题。 研究人员将与实验组密切合作，以确保新开发的方法的定量准确性。 范围：这项研究将进一步深入了解基本原子过程的性质。通过将原子理论方法扩展到受限原子，PI将原子物理学的专业知识带到了更广泛的化学和凝聚态领域。 此外，对受限原子性质的更深入了解可能会使人们深入了解一个基本上未开发的领域的新物理学，并可能开发出一种全新的设备。 PI进行了卓有成效的合作，并出版了许多联合出版物。 该项目将使美国研究生能够在印度合作机构进行研究，并将有助于两所大学的学生国际化。 此外，它将促进马德拉斯IIT建立具有国际竞争力的研究计划。

0138115MansonDescription: This award supports a US-India collaboration entitled Relativistic Effects in the Photoionization of Free and Confined Atoms. US PI Steven Manson, Georgia State University (GSU) and Pranawa Deshmukh, Indian Institute of Technology (IIT), Madras will continue to develop theoretical methodologies and perform calculations that explore ionizing collisions of electromagnetic radiation with atoms and ions. They will develop the relativistic random phase approximation (RRPA) methodology and apply it to a number of diverse problems in the area of ionization of free and confined atoms and ions by electromagnetic radiation. The investigators will work closely with experimental groups to insure quantitative accuracy of the newly developed methodologies. Scope: This research will provide further insight into the nature of fundamental atomic processes. By extending atomic theory methodology to confined atoms, the PI brings the expertise of atomic physics to bear on the broader fields of chemistry and condensed matter. Additionally, greater understanding of the properties of confined atoms may yield insight into the new physics of a largely unexplored area and possibly to the development of a whole new class of devices. The PIs have a highly productive collaboration and many joint publications to their credit. This project will enable a US graduate student to do research at the Indian collaborating institution and will contribute to internationalizing students at both universities. Additionally, it will facilitate the build-up of an internationally competitive research program at the IIT, Madras.
