Measurements of g-Factor of Rotational Band States in 82Sr

The g-factors of the positive parity rotational states up to spin I=8⁺ for the ground state band in even-even nuclei ⁸²Sr have been measured by a transient-magnetic-field ion implantation perturbed angular distribution method. The experimentally measured g-factors increase with the increasing spin along the band and show that the g_9/2 proton aligns only and the alignment starts from I=6⁺. The measured g-factors also indicate that the nuclei ⁸²Sr gain their spins by the quasi-proton alignment at higher spin.
