Abstract

The gyromagnetic ratio of the 3⁺ state (937-keV excitation energy) in ¹⁸F was measured by the time-integral IMPAC technique following implantation in a magnetically saturated Fe foil. The ¹⁶O(³He, pγ) reaction was employed using 3.75-MeV ³He⁺ beams. Measurements of the angular distribution of the de-excitation γ ray from this level to the ground state and of its precession in the hyperfine field were carried out in coincidence with backward-emitted reaction protons. The sign and magnitude determined for the g-factor of this state is g=+0.54±0.06. Shell-model calculations of the g-factor of this level have been performed and are evaluatively compared with experiment.
