The program developed by Burgess for spline fitting and interpolating collision strengths can also be used to do isoelectronic fits. Instead of treating or one inputs an arbitrary quantity that is a function of nuclear charge number Z. In this way isoelectronic atomic data can be visualised and compacted in an easy manner which allows for accurate interpolation along a sequence. Four illustrative applications are provided.
Key words: isoelectronic sequence / atomic data / spline interpolation
