Abstract
The charge transfer process between a laser-cooled magnesium ion and a ther mal barium atom in a radio-frequency ion trap in extremely low energy regim e is observed. The merit of using the trap is that the generated ions are a lso confined in the trap. The occurrence of the charge transfer process is confirmed by the detection of the laser-induced fluorescence from the gener ated ions. The cross section of the process is estimated to be 10(-3)Angstr om(2) similar to 10(-1)Angstrom(2).
