Abstract:Hyperfine interactions of12B(I pgr=1+,T 1/2=21 ms) implanted in the substitutional site of B in BN (hexagonal) was studied by detecting beta-NMR. In order to measure the quadrupole coupling constant efficiently, we employed a newly developed quadrupole resonance technique (NNQR). The quadrupole moment of12B was determined to be |Q(12B)|=13.21±0.26 mb.
