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. ***

9513091 Sellin该奖项支持田纳西大学诺克斯维尔分校的Ivan A.Sellin教授和日本筑波KEK国家高能物理实验室光子工厂的Yoisho Azuma教授之间为期三年的合作研究项目。聚集的合作者还包括田纳西大学以及来自光子工厂、东京大学和美成大学的其他教职员工、博士后和研究生。最初，联合研究将集中于解释关于锂和其他简单原子的多重激发的“空心”原子态的性质的新数据，这些原子态是在光子工厂的同步辐射共振激发下获得的，其中第一个是在本提案提交之前获得的。随后，将利用田纳西大学新开发的新的飞行时间光谱仪和配备位置灵敏探测电子设备的柱面反射镜分析器和相关软件，对相应的光电子产生及其能量和角分布进行研究。由于预计很大一部分拟议的研究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用于激光和同步辐射联合激发实验的染料激光设备进行进一步的工作，因此美日计划的目标是通过真正的双边国际合作促进科学知识的交流和转移。***
