Hyperfine structure and hyperfine anomaly in Pb

The hyperfine structure in the 6p ²-configuration in lead has been analysed and the results are compared with calculations. The hyperfine anomaly and improved values of the nuclear magnetic moment for four lead isotopes are obtained, using the results from the analysis. Using the the trend recommended adjustment of the nuclear magnetic moment in four isotopes is suggested. The results open up for new measurements of the hyperfine structure in unstable lead isotopes, in order to obtain improved values of the nuclear magnetic moment,extract information of the hyperfine anomaly and distribution of magnetisation in the nucleus.
