An atomic beam of H atoms was crossed by a pulsed beam of narrow bandwidth ( approx.700 MHz) circularly polarized tunable vuv laser radiation at lambda = 121.6 nm. The atoms were excited into a single magnetic substate in the 2p SP/sub 1/2/ level and thus polarized. This polarization is transferred via hyperfine interaction to the nucleus. A second tunable uv laser served to ionize these atoms, thereby producing nuclear-spin-polarized protons with, theoretically, 100% degree of polarization. By changing the helicity of the circularly polarized vuv laser with a quarter-wave plate, the polarization direction of the protons is changed.
