The complete pattern of Rydberg binding energies of the 18 n = 9 levels of nickel with L = 6, 7, and 8 was measured using microwave plus resonant-excitation Stark-ionization spectroscopy. The measured pattern is consistent with the form predicted with the effective potential model, showing significant structure proportional to scalar products of tensor operators of order 0-4. The variation of the structure with L separates the various contributing terms and provides determinations of several properties of the Ni + core ion. These include the quadrupole moment, Q = −0.469 78(9) a.u., the hexadecapole moment, = 0.36(5) a.u., the scalar and tensor dipole polarizabilities, α D,0 = 7.949(2) a.u., α D,2 = 0.905(12) a.u., the scalar quadrupole polarizability, α Q,0 = 55(8) a.u., the g value, g J = 1.257 (14), and the vector hyperpolarizability, β D,1 = 0.454 (24) a.u. + A 3 ( X [3] (J c ) · T [3] (r) ) + A 4 X [4] (J c ) · C [4] (r)

“…One way to measure the B + polarizability would be the RESIS technique [58,59]. The analysis of the raw experimental RESIS data can be improved if estimates of the quadrupole and non-adiabatic dipole polarizability are available.…”

A calculation of the blackbody radiation shift of the B + clock transition is performed. The polarizabilities of the B + 2s 2 1 S e , 2s2p 1 P o , and 2s2p 3 P o states are computed using the configuration interaction method with an underlying semi-empirical core potential. The recommended dipole polarizabilities are 9.64(3) a 3 0 , 7.78(3) a 3 0 and 16.55(5) a 3 0 respectively. The derived frequency shift for the 2s 2 1 S e → 2s2p 3 P o 0 transition at 300 K is 0.0160(5) Hz. The dipole polarizabilities agree with an earlier relativistic calculation (Safronova et al. Phys. Rev. Lett. 107 143006 (2011)) to better than 0.2%. Quadrupole and octupole polarizabilities and non-adiabatic multipole polarizabilities are also reported.

“…In such cases, the polarization interaction provides the dominant contribution to the energy shift. This effect is utilized in resonant excitation Stark ionization spectroscopy (RESIS) [19][20][21][22][23][24][25][26][27][28] [26], and Rnlike Th 3+ [27]. Quadrupole polarizabilities and transition matrix elements have also been determined for some of these systems.…”
