We used a computational scheme that treats relativistic and high-order electronic correlation effects within the coupled cluster with single, double, triple, and perturbative quadruple excitations (CCSDT(Q) method), as well as estimated the contribution of quantum electrodynamics and finite nuclear size effects. A systematic study of the uncertainty is carried out. This allowed us to obtain significantly refined values for the nuclear magnetic dipole and electric quadrupole moments of a wide range of odd-mass polonium isotopes. For <sup>205<\/sup>Po and <sup>207<\/sup>Po we extracted both the magnetic moment and the nuclear magnetization distribution parameter in a nuclear model-independent way. To assess the accuracy of the calculations, we also computed the ionization potential (IP), excitation energies (EEs) of the 6p<sup>4<\/sup> <sup>1<\/sup>D<sub>2<\/sub> and 6p<sup>3<\/sup>7s<sup>1<\/sup> 5S<sup>2<\/sup> electronic states, and the electronic g<sub>J<\/sub> factor in the same theoretical framework. A good agreement of the theory and experiment for IP, EEs, and g<sub>J<\/sub> confirms the reliability of the computational scheme and uncertainty estimation for the Po electromagnetic moments. We identify the 6p<sup>4<\/sup> <sup>1<\/sup>D<sub>2<\/sub> electronic level as a potentially promising state for further studies of the nuclear moments of polonium isotopes.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Leonid V.
