“…These measurements of positive ion properties provide a valuable test of calculated atomic wave functions, complementing more traditional tests such as lifetime and hyperfine structure measurements. Some of the measured properties, such as polarizabilities, are also frequently measured in neutral atoms, but others, such as the electric quadrupole moment were measured only rarely in neutral atoms [1,2] and then with far less precision than is possible in Rydberg fine-structure studies [3,4]. The quadrupole moment is a basic property of atoms with L 1, but accurate calculations require a very precise wave function [5,6].…”

Binding energies of 23 Rydberg fine-structure levels of Ni with n = 9 and L 5 were measured using resonant excitation Stark ionization spectroscopy. From this spectrum, the quadrupole moment and the scalar and tensor dipole polarizability of the 2 D 5/2 ground state of Ni + were determined to be Q = −0.474(2), α d,0 = 7.92(6), and α d,2 = 1.15(14) a.u. The electric hexadecapole moment was determined to be −0.33(21) a.u.

“…In the microwave study, the Rydberg states are prepared by neutralization of a fast ion beam [23] and resonant transition monitored via depletion of an ion current. The other study is a double resonance technique where the Rydberg level is populated through absorption of a single vacuum ultraviolet photon [24,25] monitoring field ionization as a function of millimeter wave frequency.…”

“…Since the quadrupole moment of the ionic core influences the fine-structure of nonpenetrating Rydberg states, it is possible to extract the quadrupole moment of the ion from an analysis of the Rydberg spectrum of the neutral atom [5]. The quadrupole moments of several atomic ions, including C + [5,6], Ne + [5,6,7,8,9], and N + [5,10], have been determined in this way.…”

)Atomic quadrupole moments and hyperfine constants of the metastable 2 D 3/2,5/2 states of Ca + , Sr + , Ba + , Yb + , and Hg + are calculated by the multiconfiguration Dirac-Hartree-Fock and relativistic configuration-interaction methods. For Hg + , the configuration is 5d 9 6s 2 . For the other ions, the configuration consists of a single d-electron outside a set of closed shells. Current interest in the quadrupole moments of these states is due to the fact that optical transitions of these ions may be useful as references for frequency standards. Energy shifts of the metastable states due to the interactions of the quadrupole moments with external electric field gradients are among the largest sources of error in these frequency standards. For the quadrupole moments, agreement is obtained to within about 10% with the available measurements. For the hyperfine constants, good agreement is obtained with measurements and with other calculations, except for the A factors of the 2 D 5/2 states of Sr + , Ba + , and Yb + , where the correlation effects are so large that they reverse the sign of the constant relative to the Dirac-Hartree-Fock value. As a test of the Hg + calculational methods, quadrupole moments and hyperfine constants are calculated for the 5d 9 6s 2 2 D 3/2,5/2 states in isoelectronic neutral Au. This yields a new value of the nuclear quadrupole moment Q( 197 Au) = +0.587(29) b.
