| Outline of Final Research Achievements |
We developed a new linear RF ion trap which consists of transparent electrodes, in order to perform the sensitive spectroscopy of Poincare fluorescence emitted from the isolated chain-form carbon cluster anions C4－ and C6－. Details of our new transparent ion trap was determined from the preliminary measurement using interference filters. After that we prepared the equipment required for the spectroscopy measurement. We have finished the preparation and start the observation of Poincare fluorescence with our transparent ion trap. We will perform the spectroscopy of Poincare fluorescence, owing to the high sensitivity of the developed equipment.
