Abstract
The neutron-deficient <sup>196,198</sup>Pb isotopes have been studied in Coulomb-excitation experiments employing the Miniball γ-ray spectrometer and radioactive ion beams from the REX-ISOLDE post-accelerator at CERN. The reduced transition probabilities of the first excited 2<sup>+</sup> states in <sup>196</sup>Pb and <sup>198</sup>Pb nuclei have been measured for the first time. Values of B (E2) =18.2 <inf>-4.1</inf><sup>+4.8</sup> W.u. and B( E2) =13.1 <inf>-3.5</inf> <sup>+4.9</sup>W.u., were obtained, respectively. The experiment sheds light on the development of collectivity when moving from the regime governed by the generalised seniority scheme to a region, where intruding structures, associated with different deformed shapes, start to come down in energy and approach the spherical ground state.
