“…We evaluate the uncertainties of our calculations for all of the values listed in this work. Detailed comparison of the present values with RESIS experimental results [11,27] is carried out. These calculations provide recommended values critically evaluated for their accuracy for the development of ultra precise nuclear clock, RESIS experiments with actinide ions, and other studies.…”

“…Our result is in excellent agreement with the recent RESIS measurement of Th 4+ polarizability of 7.702(6) a.u. [27]. A counter term α vc compensating for excitation from the core to the valence shell which violates the Pauli principle is also evaluated in the RPA and is given in rows labelled "vc" in Table V.…”

“…Binding energies of high-L Rydberg states (L ≥ 7) of Th 2+ with n = 27-29 were studied using the resonant excitation Stark ionization spectroscopy (RESIS) method in [11]. Analysis of the observed RESIS spectra led to determination of five properties of the Th 3+ ion: its electric quadrupole moment Θ in the ground state, adiabatic scalar and tensor ground state dipole polarizabilities, and the dipole matrix elements connecting the ground 5f 5/2 [11,27]. R is the ratio of the 5f 5/2 − 6d 3/2 and 5f 5/2 − 6d 5/2 matrix elements.…”

Atomic properties of the 24 low-lying ns, npj, ndj , nfj , and ngj states in Th IV ion are calculated using the high-precision relativistic all-order method where all single, double, and partial triple excitations of the Dirac-Fock wave functions are included to all orders of perturbation theory. Recommended values are provided for a large number of electric-dipole matrix elements, oscillator strengths, transition rates, and lifetimes. Scalar polarizabilities of the ground and six excited states (5fj , 6dj , 7pj, and 7s ), and tensor polarizabilities of the 5fj , 6dj , 7p 3/2 states of Th IV are evaluated. The uncertainties of the recommended values are estimated. These calculations provide recommended values critically evaluated for their accuracy for a number of Th IV atomic properties for use in theoretical modeling as well as planning and analysis of various experiments including development of ultra precise nuclear clock and RESIS studies of actinide ions.

Relative positions of twenty n = 28 Rydberg levels of Th 2+ with L = 9, 10, 11, and 12 were determined with sub-MHz precision using the rf-RESIS (resonant excitation Stark ionization spectroscopy) technique. The pattern of binding energies was analyzed with the effective potential model, modified to account for significant nonadiabatic effects. The analysis yielded measurements of several properties of the Fr-like Th 3+ core ion, including the quadrupole moment, Q = 0.5931( 14) a.u.; hexadecapole moment, = − 0.69(28) a.u.; g factor, g J = 1.24(48); scalar and tensor dipole polarizabilities, α D ,0 = 15.224(33) a.u. and α D ,2 = − 5.30(11) a.u.; scalar quadrupole polarizability, α Q,0 = 60(15) a.u.; and the reduced dipole and octupole matrix elements connecting the ground 5f 2 F 5/2 level with the low-lying 6d1.1) a.u. The measured properties are compared with theoretical predictions.
