Atomic and Molecular Physics with Multiply Charged Ions.

东京城市大学和Kabsa国立大学分别有4名和3名教员参加了该项目。我们共享了KSU MacDonald实验室的低温电子束离子源（EBIS）和10GHz微波电子回旋共振离子源（ECRIS），以及东京都大学的14.5GHz微波电子回旋共振离子源和紧凑型EBIS。本课题的主要目的是：(1)通过测量与高电荷离子的电荷转移反应中产生的多电荷分子的库仑爆炸，开发直接测量分子结构的新技术；(2)研究高电荷离子的电荷转移反应中的轨道共振；(3)研究高电荷离子与固体表面的相互作用。现将该方案的典型成果总结如下。(1)利用本程序研制的多点位置敏感探测器，首次观测到CD_4分子的动态手性，这是由于分子的零点振动引起的。(2)用八极束流从TMU转移到KSU，测量低能和高电荷离子与原子和分子的电荷转移截面。(3)测量高电荷离子与原子、分子的电荷转移反应中产生的离子的高激发态的磁亚能级分布。

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.
