| Research Abstract |
The existence of the electron-electric dipole moment means the evidence of new physics beyond the standard model. To achieve an experiment performing a search for the electric dipole moment, a device that can convert from francium (Fr) ions produced via the nuclear fusion reaction to neutral atoms has been developed. We achieved actually neutralizing the Fr ions and trapping stable rubidium atoms converted from positive ions. It can be said that techniques required for trapping radioactive Fr atoms was established.
