The quadrupole interaction and orbital magnetic hyperfine field of Au nuclei inFe by NMR/ON

NMR-ON measurement of the electric quadrupole interaction of199Au in Fe

“…In order to find the origin for this discrepancy we have performed precise NMR-ON measurements on 199AuF__ee. In our experiments, which are described in this paper, the quadrupole subresonances could be welt resolved, allowing a precise determination of the quadrupole splitting, which is about 20% smaller than the quadrupole splitting of [6], thus removing the discrepancy in the ratio of quadrupole moments mentioned before.…”

“…For stable isotopes such measurements can be performed with conventional NMR, while for radioactive nuclei the NMR-ON method [4] can be applied. For 198AuFce and 199AuF~e the quadrupole splittings were reported to be -1.68(16)MHz [5] and -1.78(8)MHz [6], respectively*. The corresponding ratio of quadrupole moments,…”

Hyperfine anomaly in gold and magnetic moments of Iπ=11/2− gold isomers

“…The difference between these anomalies is believed to be small (≈10% according to the estimation in Refs. [39,40]), and to determine B hf and thus the magnetic moments, the RHFA correction was taken into account in the corresponding publications. In Ref.…”
