# GRASP92: A package for large-scale relativistic atomic structure calculations

## Description

Abstract We describe a suite of programs for multiconfiguration or configuration-interaction relativistic atomic structure calculations with large configuration state function lists. Atomic orbitals are taken to be four-component spinors. Multiconfiguration self-consistent-field calculations are based on the Dirac-Coulomb Hamiltonian; at this level nuclei are assumed stationary and may be modelled either as point sources or as spherically-symmetric extended sources; in the latter case the radial varia...
