Abstract: In various applications a high nuclear polarisation, ideally a total alignment of all spins, is favourable, e.g. for sources and targets for fundamental research. The hereby presented method provides an inexpensive, fast, versatile and effective solution to produce highly polarised materials in reasonable amounts based on radio-wave pumping of hyperfine states and quantum interference effects. This method is theoretically understood and was experimentally proven for beams of metastable hydrogen atoms in the keV energy range. Thus, this technique opens the door for new applications as polarised tracers or even low-field MRI with even better spatial resolution in medicine or the production of polarised fuel to increase the energy output.
