Abstract
A set of programs developed in the department for the study of atomic structure problems is briefly described. Its core is a relativistic multiconfiguration Dirac-Fock self-consistent field program which, in various versions, can handle up to 36 orbitals and 60 configuration state functions (CSF). The system can deal with very general open-shell configurations, the necessary Racah algebra being handled automatically. The full transverse electron pair interaction, correct to O(1/c2), can be computed if desired, along with estimates of the lowest order electron self-energy and vacuum polarization corrections.Typical applications to the calculation of X-ray levels and to the interpretation of 5p excited spectra in atomic barium are briefly described.
