9513091塞尔林该奖项支持教授之间的一个为期三年的合作研究项目。诺克斯维尔的田纳西大学的塞尔林和日本筑波的KEK国家高能物理实验室光子工厂的Yoshiro Azuma教授。 合作者还包括来自田纳西大学以及光子工厂、东京大学和明成大学的其他教师、博士后和研究生。 最初，联合研究将集中精力解释有关锂和其他简单原子在光子工厂同步加速器辐射共振激发的多重激发“空心”原子态特性的新数据，其中第一个数据是在提交之前获得的。本提案。 随后，将利用新的飞行时间光谱仪和配备有位置敏感探测电子设备的柱面镜分析仪以及田纳西大学新开发的相关软件，对相应的光电子产生及其能量和角分布进行研究。由于预计所提议的研究中的很大一部分将在美国的布鲁克海文、劳伦斯伯克利和阿贡国家实验室进行，此外还将在光子工厂利用最近在那里获得的染料激光设备进行进一步的工作，用于联合激光和同步辐射激发实验，通过真正的双边国际合作促进科学知识的交流和转移的美日计划的目标是可能的。 ***

9513091 Sellin This award supports a three-year cooperative research project between Prof. Ivan A. Sellin of the University of Tennessee at Knoxville, and Prof. Yoshiro Azuma of the Photon Factory, KEK National Laboratory for High Energy Physics, Tsukuba, Japan. The collaborators assembled also include other faculty, postdocs, and graduate students from the University of Tennessee as well as from the Photon Factory, the University of Tokyo, and Meisei University. Initially, the joint research will concentrate on interpreting new data on the properties of multiply excited, "hollow" atomic states of lithium and other simple atoms resonantly excited by synchrotron radiation at the Photon Factory, the first among which was obtained just before the submission of the present proposal. Subsequently, studies of the corresponding photoelectron production and their energy and angular distributions will be undertaken, utilizing new time-of-flight spectrometers and a cylindrical mirror analyzer equipped with position-sensitive detection electronics and associated software newly developed at the University of Tennessee. As it is anticipated that a significant fraction of the proposed studies will be carried out at the Brookhaven, Lawrence Berkeley, and Argonne National Laboratories in the US in addition to further work at the Photon Factory utilizing dye laser equipment recently acquired there for use in joint laser- and synchrotron- radiation excitation experiments, the objectives of the US- Japan program in facilitating the exchange and transfer of scientific knowledge through genuinely bilateral international collaboration are likely. ***
