Abstract: The spin polarized β-emitting mirror nuclei 12B(Iπ=1+,T1/2=20.18 ms) and 12N(Iπ=1+,T1/2=11 ms) are produced by the low nuclear reactions 11B(d, p) 12B and 10B(3He,n) 12N and by selecting the projectile energy and the recoil angle. Their magnetic moments are measured by the β-NMR technique. The magnetic moments obtained after Knight shift correction are μ(12B)=1.001(17) μN and μ(12N)=0.4571(1) μN. The calculation using the existing shell model could not reproduce the measured magnetic moments for 12B and 12N simultaneously.
