Description:
Polarized beams and targets are very important tools in nuclear physics. The required polarized atoms and ions can be prepared with different methods by manipulating the occupation numbers of hyperfine substates. OPPIS@RHIC uses optical pumping with laser-induced photons between states with different main quantum number while an atomic beam source (e.g., the jet-polarimeter@RHIC) is based on filtering of unwanted hyperfine substates with Stern-Gerlach magnets and radio-wave induced transitions within the hyperfine substates. In this talk a new method will be presented that combines both technologies: Pumping with coherent and monochromatic single radio-wave pulses and quantum correlations and interferences of the induced transitions at small magnetic fields in the Zeeman region. This universal method is already proven successfully for metastable hydrogen and deuterium atoms and will be tested next at COSY for $^3$He$^+$ ions. Other possible application will be discussed as well.
