The possibility to do fundamental physics with low energy particles of antimatter and matter will be illustrated with several examples. The magnetic moment of the electron is measured to 3 part in 10^{13} with one electron suspended by itself in a trap for months at a time, and the magnetic moment of a positron similarly suspended will soon be compared. Antihydrogen atoms are being prepared for precise laser spectroscopy. The extremely strong electric field within a diatomic molecule is being exploited to look for an electron's electric dipole moment. |
