Relativistic all-order calculations of Th,Th+, andTh2+atomic properties

All-Order Methods for Relativistic Atomic Structure Calculations

All-order extensions of relativistic atomic many-body perturbation theory are described and applied to predict properties of heavy atoms. Limitations of relativistic many-body perturbation theory are first discussed and the need for all-order calculations is established. An account is then given of relativistic all-order calculations based on a linearized version of the coupled-cluster expansio...

Development of the CI + all-order method for atomic calculations

The development of the relativistic all-order method where all single and double excitations of the Dirac-Hartree-Fock wave function are included to all orders of perturbation theory led to accurate predictions for energies, transition amplitudes, hyperfine constants, and other properties of monovalent atoms as well as the calculation of parity-violating amplitudes in Cs and Fr [1]. The all-ord...

Relativistic calculations of atomic structure

This paper is intended to give a review on relativistic atomic structure calculations [1] with emphasis on the Multiconfigurational-Dirac-Foek method, Dr Crossley has summarized in his preeeeding paper most of the non-relativistic methods whieh lead to good binding energies and transition probabilities. Both quantities are espeeially important in astrophysies and plasma physies. Sinee relativis...

Relativistic SPH Calculations of Compact Binary Mergers

We review recent progress in understanding the hydrodynamics of compact binary mergers using relativistic smoothed particle hydrodynamics (SPH) codes. Recent results are discussed for both double neutron stars and black hole – neutron star binaries. The gravitational wave signals from these mergers contain a lot of information about the masses and radii of the stars and the equation of state of...
