Abstract

The g-factor of the t1/2=9.3 ns, Iπ=5/2 + state at Ex=130 keV in77Br has been measured by observation of the time differential perturbed angular correlation (PAC) in a Co single crystal. The experimental value g=1.32(1) gives evidence for large deformation, which is discussed in the framework of triaxial-rotor-plus-particle models.
