Calculation of Atomic Data for Astrophysics at University College London

Both, astrophysics and theoretical atomic physics, are pursued by the same group at University College London under the auspices of Professor M J Seaton. Through his lifelong research in both fields Mike Seaton could recognise those areas where progress in astrophysics was hampered by lack of sufficiently reliable atomic data and where further research in atomic physics was necessary to make such data available. This paper reports on methods for the calculation of atomic data employed at University College London, giving the essence of the approximations involved and some guidance as to the accuracy that can be expected from the data so produced.
