“…E P N C /β on these lines differed by ∼5% of their average value. This NSD factor was much larger than was expected, and theoretical efforts [3,6,9,13,18] to understand this result have not been successful. Meson exchange coupling constants of the so-called DDH model [19] derived from this result do not agree well with results derived from measurements of the asymmetry in the highenergy scattering of light nuclei [3,[20][21][22][23].…”

We report our detailed analysis of a table-top system for the measurement of the weak-forceinduced electric dipole moment of a ground state hyperfine transition carried out in an atomic beam geometry. We describe an experimental configuration of conductors for application of orthogonal r.f. and static electric fields, with cavity enhancement of the r.f. field amplitude, that allows confinement of the r.f. field to a region in which the static fields are uniform and well-characterized. We carry out detailed numerical simulations of the field modes, and analyze the expected magnitude of statistical and systematic limits to the measurement of this transition amplitude in atomic cesium. The combination of an atomic beam with this configuration leads to strong suppression of magnetic dipole contributions to the atomic signal. The application of this technique to the measurement of extremely weak transition amplitudes in other atomic systems, especially alkali metals, seems very feasible.

Calculation of the energies, magnetic dipole hyperfine structure constants, E1 transition amplitudes between the low-lying states, and nuclear spin-dependent parity-nonconserving amplitudes for the 2 S 1/2 -2 D 3/2,5/2 transitions in 171 Yb + ion is performed using two different approaches. First, we carried out many-body perturbation theory calculation considering Yb + as a monovalent system. Additional all-order calculations are carried out for selected properties. Second, we carried out configuration interaction calculation considering Yb as a 15-electron system and compared the results obtained by two methods. The accuracy of different methods is evaluated. We find that the monovalent description is inadequate for evaluation of some atomic properties due to significant mixing of the one-particle and the hole-two-particle configurations. Performing the calculation by such different approaches allowed us to establish the importance of various correlation effects for Yb + atomic properties for future improvement of theoretical precision in this complicated system.

“…Accurate calculations of atomic properties of heavy atoms and ions are needed for many different applications, including study of fundamental symmetries with heavy atoms [1][2][3][4], development of optical atomic clocks [5][6][7][8], study of degenerate quantum gases [9], quantum information [10], astrophysics [11], actinide chemistry [12], and many others. Recently, we have developed a theoretical method within the framework of relativistic many-body theory to accurately treat correlation corrections in atoms with few valence electrons.…”

We carry out a systematic study of Pb III properties using a hybrid method that combines configuration interaction and linearized coupled-cluster approaches. The calculations start from a [Xe]4f 14 5d 10 Dirac-Fock potential. Excitation energies and lifetimes of the 6p 2 , 6sns, 6snp, and 6snd (n 9) states are evaluated. Reduced matrix elements, oscillator strengths, and transition rates are determined for allowed electric-dipole transitions including these states. Extensive comparison with other theoretical and experimental values is carried out. Electric-dipole polarizabilities of the 6s 2 1 S 0 , 6s6p 3 P 0 , and 6s6p 3 P 1 states in Pb III and ground state polarizability of Pb 4+ are reported.
