Relativistic configuration-interaction and many-body-perturbation-theory calculations of U i hyperfine constants

Relativistic many - body calculations of energy levels , hyperfine constants , and transition rates for sodiumlike ions , Z 5 11 – 16

All-order relativistic many-body calculations of removal energies are carried out for 3s , 3p1/2 , 3p3/2 , 3d3/2 , 3d5/2 , and 4s states of sodium and sodiumlike ions with nuclear charges Z in the range 12–16. Hyperfine constants are evaluated for each state, and reduced dipole matrix elements are determined for 3p1/2-3s , 3p3/23s , 3d3/2-3p1/2 , 3d3/2-3p3/2 , 3d5/2-3p3/2 , 4s-3p1/2 , and 4s-3p...

Relativistic many-body calculations of energy levels, hyperfine constants, electric-dipole matrix elements, and static polarizabilities for alkali-metal atoms

Removal energies and hyperfine constants of the lowest four ns , np1/2 , and np3/2 states in Na, K, Rb, and Cs are calculated; removal energies of the n57 –10 states and hyperfine constants of the n57 and 8 states in Fr are also calculated. The calculations are based on the relativistic single-double ~SD! approximation in which single and double excitations of Dirac-Hartree-Fock wave functions ...

Relativistic many - body calculation of energies , lifetimes , hyperfine constants , and polarizabilities in 7

The excitation energies of ns, np, nd, and nf n 6 states in neutral lithium are evaluated within the framework of relativistic many-body theory. First-, second-, third-, and all-order Coulomb energies and firstand second-order Breit corrections to energies are calculated. All-order calculations of reduced matrix elements, oscillator strengths, transition rates, and lifetimes are given for level...
