Single particle contributions to the structure of low-lying states of Cr, Ti, Se, Zr and Nd nuclei via precision g-factor measurements

Magnetic dipole and electric quadrupole moments have traditionally been cri tical in the determination of the microscopic wave functions of particular nuclear states. Measurements on nuclei at high spin and energy, as well as on nuclei in superdeformed states have yielded a wealth of information on t heir structure. The techniques developed for these measurements are now bei ng extended to the study of nuclei far-from-stability such as those which w ill be accessible via reactions with radioactive beams. Very precise determ inations of the magnetic moments of the 2(1)(+) states of Cr, Ti, Zr, Se an d Nd isotopes, recently carried out via "projectile excitation", place very tight constraints on existing nuclear models, from single particle calcula tions in the 1fp shell to extended IBM models, and further highlight the im portance of the interplay between single particle and collective excitation s across the table of isotopes. The experimental results will be presented and compared with theoretical calculations.
