Four and three faculty members attended this program from Tokyo metropolitan University and Kabsa State University, respectively. We shared a cryogenic electron beam ion source (EBIS) and an electron cychrotron resonance ion souce (ECRIS) with 10GHz micro wave at MacDonald Laboratory of KSU as well as an ECRIS with 14.5GHz micro wave and compact EBIS in Tokyo Metropolitan University. Main purposes of this project are (1) developmemnt of new technique to measure molecular structures directly by measuring Coulomb explosion of multiply charged molecules produced in charge transfer reaction with highly charged ion, (2) study of orbitting resonances in charge transfer reactions of highly charged ions, (3) study of interactions of highly charged ions with solid surfaces.Typical results of this program is summerized as follows.(1) First observation of dynamic chirality of CD_4 molecules appeared due to zero point vibration of molecules by using a multi-hits position-sensitive detector developed in this program.(2) Measurement of charge transfer cross sections of low energy and highly charged ions with atoms and molecules with an octa-pole beam suide transfered from TMU to KSU.(3) Measurement of distributions of magnetic sub levels of highly excited states of ions produced in charge transfer reactions of highly charged ions with atoms and molecules.

来自东京都大学和卡布萨国立大学的四名和三名教职员工分别参加了这一项目。我们共用KSU麦克唐纳实验室的低温电子束离子源(EBIS)和10 GHz微波的电子回旋共振离子源(ECRIS)，以及东京市立大学的14.5 GHz微波ECRIS和紧凑的EBIS。本项目的主要目的是：(1)发展通过测量高电荷离子电荷转移反应中产生的多电荷分子的库仑爆炸来直接测量分子结构的新技术；(2)研究高电荷离子电荷转移反应中的轨道共振；(3)高电荷态离子与固体表面相互作用的研究.本程序的典型结果概括如下：(1)利用本程序研制的多重击位置灵敏探测器首次观测到了分子零点振动引起的CD_4分子的动态手性.(2)用八极束流从TMU转移到KSU测量了低能和高电荷态离子与原子和分子的电荷转移截面.(3)测量了高电荷态离子与原子和分子电荷转移反应中产生的高激发态离子的磁子能级分布.
