The g factor of the 44Cl ground state is measured at the LISE fragment separator at the Grand Acclérateur National d’Ions Lourds (GANIL) using the β nuclear magnetic resonance technique, resulting in g(44Cl)=(-)0.2749(2). An analysis of the g factor value and of the theoretical level scheme in the shell-model framework reveals the presence of odd-proton s1/2 configurations and neutron excitation across the N=28 shell gap in the ground state of 44Cl. In addition, the measured g factor strongly supports a 2 spin assignment for the 44Cl ground state.

Using new techniques developed for measuring angular correlations with large detector arrays, the g factors of 2+ states in 140,142Xe are measured for the first time by the method of correlation attenuation in randomly oriented magnetic fields. g factors in 146Ba and 146,148Ce are measured to establish the method by comparison with previous values. The results are discussed in terms of IBM-2 and rotation-vibration models.
