Abstract

The $g$ factor of the ${}^{44}{Cl}$ 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 $g$ ( ${}^{44}{Cl}$ ) $= (-) 0.2749 (2)$ . 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 ${}^{44}{Cl}$ . In addition, the measured $g$ factor strongly supports a $2^{-}$ spin assignment for the ${}^{44}{Cl}$ ground state.
