Our new commutation technique for excitons interacting with electrons allowed us to derive the X− trion expansion in terms of exciton–electron pairs while taking exactly into account the fact that the exciton can be made with any of the two electrons.

Journal of Quantitative Spectroscopy and Radiative Transfer, 1985
Abstract Oscillator strengths of 150 Ni I lines in the spectral range 2800–6200 A have been obtained by emission and from hook measurements. Relative sets of ƒ-values were determined by combining emission measurements on a hollow cathode with hook measurements in a high-temperature furnace.

Oscillator strengths in porphyrins
Chemical Physics Letters, 1971Abstract Oscillator strengths for D 4h and D 2h porphyrins are calculated using the dipole gradient formulation and compared with calculations employing the dipole length operator. The effect of configuration interaction is also discussed.

Oscillator strengths for helium
Canadian Journal of Physics, 1970Oscillator strengths for 95 singlet and triplet s–p and p–d transitions in neutral helium have been calculated using analytical wave functions of the "frozen-core" type. Both length and velocity formulations of the oscillator strengths have been employed. Our results are generally in good agreement with the most accurate values available.

Abstract Accurate multiconfiguration Hartree-Fock (MCHF) ƒ-values are compared with the most reliable theoretical values obtained by other theories and recent laser beam experiments. For the 2 3 S-2 3 P transition in Li II, MCHF results are in excellent agreement with those of Schiff et al.

By a combination of hook and emission measurements oscillator strengths of 122 Fe I lines have been determined without any assumption concerning the plasma state. For the hook and emission measurements, a graphite furnace and a hollow cathode have been used as light sources.

Computing Oscillator Strengths and Related Properties
AIP Conference Proceedings, 2007Based on recent monographies by Yngve ÖHRN, the central role of transition dipole moments for determining molecular properties is highlighted. In particular, the focus is placed on oscillator strengths, polarizabilities, and hyperpolarizabilities.

Physical Review, 1962
Cesium oscillator strengths are calculated using oneelectron wave flunctions. These functions are numerical solutions of the Schrodinger equation with a central, symmetric potential and with the spin-orbit term. The potential is chosen so that the binding energies of the lowest ten levels agree with spectroscopic values to 3%; the next 30 levels agree ...
