A Hartree-Fock program for atomic structure calculations

The Hartree-Fock equations for a general open shell atom are described. The matrix equations that result when the single particle orbitals are written in terms of a linear combination of analytic basis functions are derived. Attention is paid to the complexities that occur when open shells are prese nt. The specifics of a working FORTRAN program which is available for publi c use are described. The program has the flexibility to handle either Slate r-type orbitals or Gaussian-type orbitals.
