The research continues development of theoretical methodologies and calculations that explore ionizing collisions of electromagnetic radiation and charged particles with matter.The work stresses the need to account for many-body interactions which dominate many photoionization and photodetachment processes. The study will also encompass the spectra of electrons ejected in many of these collisions and how that is crucial to understanding the deposition of energy by radiation in matter. Finally, the work will continue previous studies of the interaction of radiation with confined atoms and ions, e.g., confined in fullerenes or quantum dots. Of great importance will be the realistic handling of the confining potential of systems such as C60. Particular emphasis shall be placed upon the how the details of the confinement alters the properties of free atoms and ions.

该研究继续发展理论方法和计算，探索电磁辐射和带电粒子与物质的电离碰撞。这项工作强调需要考虑主导许多光电离和光分离过程的多体相互作用。 这项研究还将包括在许多这些碰撞中喷射出的电子的光谱，以及这对理解物质中辐射能量沉积的重要性。最后，这项工作将继续以前对辐射与受限原子和离子相互作用的研究，例如，局限在富勒烯或量子点中。 非常重要的将是现实的处理限制潜力的系统，如C60。特别强调的是如何限制的细节改变自由原子和离子的属性。
