Zusammenfassung:
We report the first measurement of the magnetic dipole and electric quadrupole moment of the exotic nucleus 133Sn by high-resolution laser spectroscopy at ISOLDE/CERN. These, in combination with state-of-the-art shell-model calculations, demonstrate the single-particle character of the ground state of this short-lived isotope and, hence, the doubly-magic character of its immediate neighbor 132Sn. The trend of the electromagnetic moments along the N=83 isotonic chain, now enriched with the values of tin, are discussed on the basis of realistic shell-model calculations.
