Abstract
Binding energies of high- Rydberg levels of Th were measured using the resonant excitation Stark ionization spectroscopy technique. Analysis of the data with the long-range polarization model leads to determination of dipole and quadrupole polarizabilities of the free Th ion, 7.61(6) a.u., 47(11) a.u.
