- Systematic multiconfiguration Hartree-Fock results are presented for the transition probabilities and excited-state lifetimes in the term system of the boron atom. Particularly, the interaction between the 1s(2)2s2p2 configuration and the 1s(2)2s2ns2S and 1s(2)2s2nd2D Rydberg series is considered. Term energies and transition-matrix elements are calculated to convergence using increasing active sets of s, p, d, f, and g orbitals.

Tidskriftsartikel (refereegranskat)abstract
- Hyperfine structure constants for the ground and first excited states of sodium are calculated using a newly written hyperfine structure program, which is part of the MCHF Atomic Structure Package. The calculated hyperfine structure constants are compared with the most reliable values obtained in other theoretical studies and in experiments. Also, a new accurate experimental determination of the 3p P-2(1/2) state hyperfine structure is presented.

Tidskriftsartikel (refereegranskat)abstract
- The MCHF_LSGEN program systematically generates coupled configuration states needed for accurate MCHF studies. All possible couplings and configuration states are made of multi-replacements from several reference sets.
