The g factor of the Cl-44 ground state is measured at the LISE fragment separator at the Grand Accelerateur National d'Ions Lourds (GANIL) using the beta nuclear magnetic resonance technique, resulting in g(Cl-44) = (-)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 s(1/2) configurations and neutron excitation across the N = 28 shell gap in the ground state of Cl-44. In addition, the measured g factor strongly supports a 2(-) spin assignment for the Cl-44 ground state.status: publishe
