For the first time, we obtained the g factor for the ground state of Al23 by use of a β-NMR measurement. Al23 has a small proton separation energy and is a potential proton-halo candidate. The obtained g factor, |g|=1.557±0.088, clearly shows the spin and parity, Jπ=5/2+, for Al23, which is the same as that of its mirror partner, Ne23. The possible nuclear structure of Al23 is also discussed.
