| Outline of Final Research Achievements |
We are constructing a gas-phase NMR apparatus of molecular ions based on a Stern-Gerlach type detection technique using a Penning trap (NMR cell). In this method, ultracold molecular ions are introduced in the cell and its magnetic resonance is probed by observing the modulation of their TOFs induced by the RF magnetic excitation at both ends of the cell. Thus, the preparation and manipulation of cold ions under the strong magnetic field are the basic techniques of this method. We present new experimental techniques and the results on cold trimethylamine ions with translational temperature of less than 1 mK, which are prepared through deceleration, slicing, and bunching of the ions generated by the photoionization of supersonically cooled trimethylamine. We also developed a RF magnetic excitation system for the NMR detection. Using these techniques, we are conducting a proof of principle experiment of new NMR method for gas-phase ions.
