Abstract/OtherAbstract:
In-source resonant ionization laser spectroscopy of the even-A polonium isotopes ^{192-210,216,218}Po has been performed using the 6p^{3}7s ^{5}S_{2} to 6p^{3}7p ^{5}P_{2} (λ=843.38  nm) transition in the polonium atom (Po-I) at the CERN ISOLDE facility. The comparison of the measured isotope shifts in ^{200-210}Po with a previous data set allows us to test for the first time recent large-scale atomic calculations that are essential to extract the changes in the mean-square charge radius of the atomic nucleus. When going to lighter masses, a surprisingly large and early departure from sphericity is observed, which is only partly reproduced by beyond mean field calculations.
