What it covers
Laser-spectroscopy determination of the hyperfine anomaly and the magnetic moments of the long-lived Iπ=11/2⁻ isomers in gold.
Methods and setup
In-source or collinear laser spectroscopy of gold isomer beams at ISOLDE. The hyperfine anomaly is the leftover difference once the point-nucleus magnetic moment is accounted for.
Why it matters
The anomaly is a rare window on the magnetisation distribution inside the nucleus. Gold isomers next to the mercury shape region are where that distribution changes with deformation.
