Abstract	High-precision mass measurements of neutron-deficient Tl (A=184, 186, 190, 193–195, 198) isotopes as well as Pb (A=202,208), Fr (A=207,208), and Ra (A=224) are performed with the Penning-trap mass spectrometer ISOLTRAP at ISOLDE/CERN. The improved precision of the mass data now allows the study of subtle odd-even effects. The gradual development of collectivity with the removal of protons from the magic Z=82 core is analyzed by combining the new mass results with nuclear charge-radii data and mean-field model predictions.
