Abstract
Beta-detected nuclear quadrupole resonances () at zero field are observed using a beam of low energy highly polarized radioactive 8Li+. The resonances were detected in SrTiO3, Al2O3 and Sr2RuO4 single crystals by monitoring the beta-decay anisotropy as a function of a small audio frequency magnetic field. The resonances show clearly that 8Li occupies one site with non-cubic symmetry in SrTiO3, two in Al2O3 and three sites in Sr2RuO4. The resonance amplitude and width are surprisingly large compared to the values expected from transitions between the | 2> | 1> spin states, indicating a significant mixing between the | m>$ quadrupolar split levels.
