| Research Abstract |
Effect of structure of carbon chain negative ions in cooling process in vacuum was investigated with electrostatic ion storage rings with two different circumferences. By using an ion storage ring with circumference of about 7.7 m, laser-induced electron detachment with delays up to several milliseconds was observed. It was revealed that the terminal hydrogen atom caused a drastic change in the decay profiles. Meanwhile, a tabletop ion storage ring with circumference of about 0.8 m is constructing in order to observe cooing processes up to a few milliseconds. Problems associated with miniaturization and discharge among electrodes are being solved to achieve ion storage with the tabletop ring.
