Abstract

Interpolation formulas, having functional forms inspired by Padé approximants, and containing at most three parameters, have been derived for a number of atomic oscillator strengths. It is shown that very accurate results are obtained both for specific transitions in the helium and lithium isoelectronic sequences, and for certain series in hydrogen, helium, and lithium. Application of our methods to other systems is prevented only by the lack of reliable input and comparison data.
