dc.description.abstractCoulomb-excitation experiments are performed with postaccelerated beams of neutron-deficient 196,198,200,202Po isotopes at the REX-ISOLDE facility. A set of matrix elements, coupling the low-lying states in these isotopes, is extracted. In the two heaviest isotopes, 200,202Po, the transitional and diagonal matrix elements of the 2+ 1 state are determined. In 196,198Po multistep Coulomb excitation is observed, populating the 4+ 1 , 0+ 2 , and 2+ 2 states. The experimental results are compared to the results from the measurement of mean-square charge radii in polonium isotopes, confirming the onset of deformation from 196Po onwards. Three model descriptions are used to compare to the data. Calculations with the beyond-mean-field model, the interacting boson model, and the general Bohr Hamiltonian model show partial agreement with the experimental data. Finally, calculations with a phenomenological two-level mixing model hint at the mixing of a spherical structure with a weakly deformed rotational structure.
