To generate metastable hydrogen atoms in single hyperfine substates, a spin filter has been used at the Institute for Nuclear Physics at the Research Center Jülich since 2001. That spin filter can select the various states to then measure the nuclear spin polarisation of an atomic beam of hydrogen and deuterium from the intensity ratio of the Lyman-α transitions occurring during Stark quenching.Such a spin filter is capable of filtering the two 2S_1/2-α hyperfine structure states of an excited atom.
