用极化放射性核束和β-NMR探测相结合的方法，首次测定了质子滴线核13 O（Iπ = 3/2-，T1/2= 8.6 ms）和9 C（Iπ= 3/2-，T1/2= 126 ms）的磁矩。观测到的磁矩为：δ μ（13 O）β = 1.3891 ±0.0003μ N，δ μ（9 C）β = 1.3914 ±0.0005μN。对13 O和9 C的自旋期望值分别为0.76和1.44。虽然13 O的<σ>与同位旋T = 1/2镜像对的系统学一致，但9 C的<σ>异常大，甚至远大于单个粒子的<σ> = 1。
The magnetic moments of the proton drip-line nuclei13O(Iπ= 3/2−,T1/2= 8.6 ms) and 9C(Iπ= 3/2−,T1/2= 126 ms) have been determined for the first time through the combined techniques of polarized radioactive nuclear beams andβ-NMR detection. The observed magnetic moments are ¦μ(13O)¦ = 1.3891 ±0.0003μNand ¦μ(9C)¦ = 1.3914 ±0.0005μN. Spin expectation values <σ> are deduced to be 0.76 and 1.44 for13O and9C, respectively. While the <σ> of13O is consistent with the systematics from isospinT= 1/2 mirror pairs, the <σ> of9C is unusually large, even far larger than the single particle value, <σ> = 1.
