Abstract

The $g$ factors of the first-excited states of stable $^{124}$ Sn and radioactive $^{126, 128}$ Sn were measured by the recoil-in-vacuum method with comparatively high precision. The experiments were performed at the Holifield Radioactive Ion Beam Facility by Coulomb exciting $\sim 3$ MeV/u beams in inverse kinematics on carbon and titanium targets. The results for $^{124}$ Sn and $^{126}$ Sn are in excellent agreement with recent shell-model calculations. For $^{128}$ Sn the experiment suggests an increase in the magnitude of $g (2_{1}^{+})$ , as predicted by some models. The present results provide a sensitive probe of the valence orbitals that contribute to the $2_{1}^{+}$ wave functions as the double-shell closure at $^{132}$ Sn is approached.
