Query: Hyperfine structure and hyperfine anomaly in Pb   The hyperfine structure in the 6p2-configuration in lead has been analysed
and the results is compared with calculations. The hyperfine anomaly and
improved values of the nuclear magnetic moment for four lead isotopes is
obtained, using the results from the analysis. The results open up for new
measurements of the hyperfine structure in unstable lead isotopes, in order to
extract information of the hyperfine anomaly and distribution of magnetisation
in the nucleus.
