Abstract
The multiconfiguration Hartree-Fock method extended to include relativistic effects in the Breit-Pauli approximation (MCHF-BP) is tested in the study of the ground configuration of nitrogen-like ions. Fine-structure splittings, E2 and M1 transition rates calculated with the classical (nonrelativistic) form of the magnetic transition operator are presented and compared with other theoretical and experimental results up to Zn XXIV. The astrophysical problem of the high-density limit of the intensity ratio I(2D5/2 to 4S3/2)/I(2D3/2 to 4S3/2) is discussed on the basis of these new theoretical data.Keywords
