利用11B（d，p）12 B核反应和入射氘能量及反应后12 B反冲角的选择技术，产生了自旋极化β发射核12 B（Iπ=1+，T12 = 20.18ms）。利用国内首次建立的β-NMR和β-NQR装置，用β-NMR测量了短寿命核12 B的磁矩。经Knight位移精确校正后，测得~（12）B的磁矩为μ=0.99993±0.00048 nm，org=0.99993±0.00048。
The spin polarized β-emitting nuclei12B (Iπ=1+,T1/2=20.18 ms) were produced by the nuclear reaction11B(d, p)12B and by the selection technique of the incident deuteron energy and the12B recoil angle following the nuclear reaction. The nuclear magnetic moment of the short-lived nuclei12B was measured by β-NMR with the β-NMR and β-NQR setup established for the first time in China. The nuclear magnetic moment of12B was determined to be μ=0.99993±0.00048 nm org=0.99993±0.00048 after the precise correction of the Knight shift.
