Relativistic many-body calculation of energies, lifetimes, hyperfine constants, and polarizabilities in Li
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...
متن کاملNuclear-polarization effect to the hyperfine structure in heavy multicharged ions
We have investigated the correction to the hyperfine structure of heavy multicharged ions, which is connected with the nuclear-polarization effect caused by the unpaired bound electron. Numerical calculations are performed for hydrogenlike ions taking into account the dominant collective nuclear excitations. The correction defines the ultimate limit of precision in accurate theoretical predicti...
متن کاملRelativistic 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...
متن کاملQuantum Many–Body Problems and Perturbation Theory
We show that the existence of algebraic forms of exactly-solvable A−B− C−D and G2, F4 Olshanetsky-Perelomov Hamiltonians allow to develop the algebraic perturbation theory, where corrections are computed by pure algebraic means. A classification of perturbations leading to such a perturbation theory based on representation theory of Lie algebras is given. In particular, this scheme admits an ex...
