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.

四名和三名教职员工分别参加了东京都会大学和卡布萨州立大学的该计划。我们在KSU的Macdonald Laboratory以及一个具有14.5GHz Micro Wave和Compact Ebis Ebis Ebis in Tokyo Metropolitatan University In Tokyo Metropolitan University中的ECRIS，共享了带有10GHz微波的电子晶束离子源（EBI）和一个带有10GHz微波的电子Cychrotron共振离子SOUCE（ECRIS）。该项目的主要目的是（1）开发新技术，通过测量用高电荷离子中电荷转移反应产生的多重电荷分子的库仑爆炸来直接测量分子结构，（2）（2）研究中电荷转移反应的轨道共振反应高电荷转移反应离子，（3）研究高电荷离子与固体表面的相互作用。该程序的典型结果如下所示。（1）由于使用多种多数而通过使用多种多数分子的零点振动，出现了CD_4分子动态手性的首次观察。 （2）测量低能和高电荷离子的电荷转移横截面的测量，其原子和分子具有从TMU转移到KSU的八杆束束固定的原子和分子。（3）测量的测量高电荷离子与原子和分子的电荷转移反应产生的高度激发态的磁子水平。
