Atomic and Molecular Physics with Multiply Charged Ions.

东京都立大学和Kabsa州立大学分别有四名和三名教员参加了该项目。我们在KSU的MacDonald实验室共享了一台10 GHz微波的低温电子束离子源（EBIS）和一台电子回旋共振离子源（ECRIS），在东京首都大学共享了一台14.5GHz微波的ECRIS和紧凑型EBIS。本项目的主要目的是：（1）发展通过测量多电荷分子与高电荷态离子发生电荷转移反应时的库仑爆炸直接测量分子结构的新技术;（2）研究高电荷态离子电荷转移反应中的轨道共振;（3）研究高电荷态离子与固体表面的相互作用。(1)利用研制的多点位置灵敏探测器首次观测到了CD_4分子的零点振动所引起的动态手性。(2)用八极束流测量低能高电荷态离子与原子和分子的电荷转移截面。(3)高电荷态离子与原子、分子电荷转移反应中离子高激发态磁子能级分布的测量。

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.
