Abstract
Rigorous upper and lower bounds are prescribed in the form of approximate quadratures for a variety of oscillator-strength sums. The required integration points and weights are determined from continued-fraction approximants and linear programming techniques, employing oscillator-strength moments as inputs to the method. Illustrative bounds are provided in the cases of atomic hydrogen, helium, and neon, for odd-integer sums and for the mean energies associated with stopping, straggling, excitation, and the Lamb shift.
