Abstract Hyperfine interactions of12B(I π,T 1/2=21 ms) implanted in the substitutional site of B atoms (stable) in a (single crystal like) BN (hexagonal) was studied by use of a β-NMR detection. For efficient and simple measurements, the conventional β-NMR has been modified as a new nuclear quadrupole resonance technique (NNQR). For the present case with the nuclear spinI=1 the detection efficiency is improved about 30 times compared with the one with the old method. The quadrupole moment of12B was determined precisely as ¦Q(12B; 1+)¦=13.21±0.26 mb.
