THE INTRODUCTION OF B-SPLINE BASIS-SETS IN ATOMIC-STRUCTURE CALCULATIONS

We review some of the progress which has been achieved in calculations of atomic structure over the last few years, especially connected wit h the introduction of B-spline basis sets. The most important property of these basis sets is that they are effectively complete even in the case of a rather small set of basis functions. The possibilities for systematic calculations are discussed and applications to configuratio n interaction calculations as well as to calculations based on many-bo dy perturbation theory are reviewed.
