| Zusammenfassung | We report on a new method to perform rf-resonance spectroscopy of stable terms in atoms and ions. Fast 14N+ ions are scattered under grazing incidence from a flat surface, where stable atomic terms are populated preferentially and polarized with respect to their orbital angular momenta and nuclear spins. By a modification of this polarization via magnetic dipole transitions induced by a resonant rf field, we have measured the hf structures of most stable terms in 14N I, II, III and deduce from our data the nuclear electric quadrupole moment of 14N with improved precision: Q(14N)=20.0±0.2 mb. |
