| Abstract: | Hyperfine interactions of 12,14N in BN(hexagonal) crystal were studied by detecting β-NQR(12N) and FT-NMR(14N). A β-NMR of 16N (I
π=2−,T
1/2=7.13 s) in MgO crystal was detected to determine the magnetic moment of 16N to be |μ(16N:2−)|=(1.986±0.001)μN. Also, the β-NQR of 12,16N in TiO2 crystal were detected to determine |Q(16N:2−)|=(17.9±1.7) mb. An abnormally small effective charge for neutrons is required to account for |Q(16N:2−)|.
