Abstract

Perturbed angular correlations were measured between 1.98-MeV γ rays de-exciting the 3.3-psec 2+ state of O18 and the O*18 particles following the reaction C12(O18, O*18)C12 at 33 MeV. A magnetic spectrometer was used to resolve the O*18 ions into the component 8+, 7+, and 6+ charge states, and the correlations were determined separately for each. The measurements yield information on hyperfine interactions in the 7+ and 6+ charge states. Limits are obtained on the ionic ground-state occupancies and on the value of the nuclear g factor.
