CHARGE TRANSFER BETWEEN A LASER-COOLED ION AND A THERMAL ATOM
 IN A RADIO-FREQUENCY TRAP

The charge transfer between a laser-cooled magnesium ion and a thermal
barium atom in a radio-frequency ion trap is observed.
The merit of using the trap is that the generated ion is confined.
The charge transfer is confirmed by the laser-induced fluorescence.
