项目摘要

The following resulted from the collaboration with the British scientists : (1) As an example of highly charged ions , the electron - impact excitation cross sections for He - like ions ( S XV, etc. ) have been calculated using the R - matrix theory including the relativistic effects , and their behavior along the isoelectronic was analyzed . (2) As another example of highly charged ions , the electron - impact excitation cross sections for the Ca - like ions Fe VII have also been calculated using the R - matrix theory and they have been compared with the cross sections for other cases . (3) One of the multiply excited hollow atoms that attract much recent interest , I. e. , formation of triply excited hollow Li atoms by photon impact was calculated by the R - matrix method . The results were compared with the recent SR experiments . (4) For the purpose of studying the peculiar physics of collisions of atoms with negatively Charged particles , the formation of antiprotonic atoms in collisions of antiprotons with atoms was studied using the classical trajectory Monte Carlo method . (5) As a peculiar collision system , low - energy ion - atom collisions in a strong magnetic field was treated theoretically and their cross sections were calculated .Japan - UK seminar was held at RIKEN on July 30 , 31 and August 1 , 1999 to present and discuss the results of Japan - UK collaboration resulting from the present collaboration program . Other researches going on in Japan and in UK were also presented and possible future collaborations are discussed .

（1）以高电荷态离子为例，用考虑相对论效应的R矩阵理论计算了类He离子（S XV等）的电子碰撞激发截面，并分析了它们沿等电子线的沿着行为。(2)作为高电荷态离子的另一个例子，用R矩阵理论计算了类钙离子Fe VII的电子碰撞激发截面，并与其它情况下的截面进行了比较。(3)作为近年来备受关注的多重激发空心原子之一，I。e.用R矩阵方法计算了三重激发的空心Li原子的光子碰撞形成过程。与最近的SR实验结果进行了比较。(4)为了研究原子与带负电荷粒子碰撞的特殊物理过程，用经典的轨道蒙特卡罗方法研究了反质子与原子碰撞中反质子原子的形成. (5)作为一种特殊的碰撞系统，对强磁场中低能离子-原子碰撞进行了理论处理，并计算了碰撞截面。1999年7月30日、31日和8月1日在理化学研究所举行了日英研讨会，介绍和讨论了本合作计划所产生的日英合作成果。在日本和英国进行的其他研究也被提出，并讨论了未来可能的合作。
