首次用核磁共振方法测定了{sup 23}Al的基态g因子。Al具有较小的质子分离能，是一种潜在的质子晕候选者。得到的g因子，垂直条g，垂直条=1.557{+-0.088，清楚地显示了{sup 23}Al的自旋和宇称J{sup{pi}}=5/2{sup+}，这与它的镜像对{sup 23}ne的自旋和宇称相同。讨论了{sup 23}Al可能的核结构。
For the first time, we obtained the g factor for the ground state of {sup 23}Al by use of a {beta}-NMR measurement. {sup 23}Al has a small proton separation energy and is a potential proton-halo candidate. The obtained g factor, vertical bar g vertical bar =1.557{+-}0.088, clearly shows the spin and parity, J{sup {pi}}=5/2{sup +}, for {sup 23}Al, which is the same as that of its mirror partner, {sup 23}Ne. The possible nuclear structure of {sup 23}Al is also discussed.
