Excitation energies, polarizabilities, multipole transition rates, and lifetimes of ions along the francium isoelectronic sequence
U. I. Safronova, W. R. Johnson, M. S. Safronova
Relativistic many-body perturbation theory is applied to study properties of ions of the francium isoelectronic sequence. Specifically, energies of the 7s, 7p, 6d, and 5f states of…
High-precision study of Cs polarizabilities
E. Iskrenova-Tchoukova, M. S. Safronova, U. I. Safronova
We present results of the first-principles calculation of Cs dipole static polarizabilities for the Ns (N = 6 - 12), Np_j (N = 6 - 10), and Nd_j (N = 5 - 10) states using the relat…
Excitation energies, polarizabilities, multipole transition rates, and lifetimes in Th IV
U. I. Safronova, W. R. Johnson, M. S. Safronova
Excitation energies of the ns_{1/2} (n=7-10), np_j (n=7-9), nd_j (n=6-8), nf_{j} (n=5-7), and ng_{j} (n=5-6) states in Th IV are evaluated. First-, second-, third-, and all-order C…
Excitation energies, hyperfine constants, E1, E2, M1 transition rates, and lifetimes of (6s2)nl states in Tl I and Pb II
U. I. Safronova, M. S. Safronova, W. R. Johnson
Energies of np (n=6-9), ns (n=7-9), nd (n=6-8), and nf (n=5-6) states in Tl I and Pb II are obtained using relativistic many-body perturbation theory. Reduced matrix elements, osci…
Excitation energies, oscillator strengths, and lifetimes of levels along the gold isoelectronic sequence
U. I. Safronova, W. R. Johnson
Energies of ns[1/2] (n= 6-9), np[j] (n = 6-8), nd[j] (n= 6-7), and 5f[j] states in neutral Au and Au-like ions with nuclear charges Z = 80 - 83 are calculated using relativistic ma…
Finite-field evaluation of the Lennard-Jones atom-wall interaction constant C_3 for alkali-metal atoms
W. R. Johnson, V. A. Dzuba, U. I. Safronova +1
A finite-field scaling method is applied to evaluate the Lennard-Jones interaction constant C_3 for alkali-metal atoms. The calculations are based on the relativistic single-double…
