Abstract : The g factor of the 44Cl ground state is measured at the LISE fragment separator at the Grand Accélérateur 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.
