Collision strengths and oscillator strengths for Fe IX
Atomic Data and Nuclear Data Tables, 1991Abstract Collision strengths and oscillator strengths are calculated for Fe IX. The three configurations 3 s 2 3 p 6 , 3 s 2 3 p 5 3 d , and 3 s 2 3 p 5 4 s were included in the computations. The data can be applied to the analysis of spectral lines in the solar spectrum and laboratory sources. The collision calculations were executed with the

Optical phonons with a negative oscillator strength
Physics-Uspekhi, 2020Abstract We discuss the nature of additional (redundant from the point of view of selection rules) optical phonons observed in most crystals with ion–covalent bonds between atoms, including in their solid solutions.

Eigenenergies and oscillator strengths for the Hulthén potential
Physical Review A, 1990A detailed study of the bound-state properties of the Hulth\'en potential is presented. Accurate eigenenergies are obtained for the Hulth\'en potential by numerical integration of the Schr\"odinger equation. One-parameter variational calculations are carried out.

Recent Advances in the Calculation of Oscillator Strengths
Physica Scripta, 1977A review of work published since the last beam-foil spectroscopy conference in Gatlinburg (1975) is presented. For allowed transitions whereLScoupling is valid, the NCMET and FOTOS schemes are compared and an extension of the application of FOTOS is proposed.
