Abstract
The nuclear quadrupole interaction of short-lived β-emitter 12N(I=1, T 1/2=11 ms) implanted into a ZnO single crystal has been studied by means of the β-NMR method. We have observed a quadrupole splitting of 12N in ZnO at room temperature, from which the electric field gradient (EFG) q=+(8.6 ±1.1)×1019 V/m2 was deduced assuming axially symmetric EFG with respect to the crystalline c axis. A first principle calculation does not reproduce the data under assumption of the lattice location of 12N at the oxygen substitutional site.
