The theoretical evaluation of major nuclear structure effects on the asymmetry of allowed GamowTeller β-decay rates in light mirror nuclei is presented. The calculations are performed within the shell model, using empirical isospin-nonconserving interaction and realistic Woods-Saxon radial wave functions. The revised treatment of p-shell nuclei is supplemented by systematic calculations for sdshell nuclei and compared to experimental asymmetries when available. The results are important in connection with the possible existence of second-class currents in the weak interaction.

“…Therefore, the quadrupole coupling constant eqQ/ h[ 12 N in ZnO] = +(20 ± 2) kHz, was deduced. Using known quadrupole moment Q[ 12 N] = +(9.6 ± 0.8) mb [6,7], the EFG was deduced as q = +(8.6 ± 1.1) × 10 19 V/m 2 . Δν (kHz)…”

The nuclear quadrupole interaction of short-lived β-emitter 12 N(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 12 N in ZnO at room temperature, from which the electric field gradient (EFG) q = +(8.6 ± 1.1) × 10 19 V/m 2 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 12 N at the oxygen substitutional site.

“…The first errors in eqQ/h in Table I are the statistical errors and the second errors are the systematic errors caused by the unknown origin of Sub resonance. One-tenth of the width (THWHM) of Main resonances is considered as the systematic errors [4].…”
