Perturbed γ–γ correlations from oriented nuclei and static moment measurements. II: g factors at low spin and high spin

Abstract

The perturbations of γ–γ directional correlations from nuclei oriented by heavy-ion induced reactions, as observed with a multidetector array, are employed to measure the magnetic dipole moments of sub-nanosecond excited states in neutron-deficient nuclei. The technique is compared with other techniques for measuring g factors of short-lived excited states. Some representative results, which use transient hyperfine fields to measure g factors at high spin and static hyperfine fields to measure g factors at low spin, are presented.
