Abstract The hfs of205Pb in the 283.3-nm resonance line and its isotope shift (IS) have been measured in absorption with the use of dispersive spectroscopy. A new method for calibration and analysis, when internal standards are not available is described. The results are: hfs interaction constantsA=70.3(5)×10−3 cm−1,B=−0.6(1.1)×10−3 cm−1,205Pb-208Pb IS=−123.9(2.0)×10−3 cm−1. The derived nuclear magnetic dipole moment,μ=0.704(5)μ N is in good agreement with values calculated with a nuclear configuration mixing model.
