On the oscillator strength of the resonance transitions of Sr+
Journal of Quantitative Spectroscopy and Radiative Transfer, 1970Abstract Density measurements by the resonance flourescence scattering method and other diagnostic techniques in an Sr plasma, produced by contact ionization, yield for the ratio of the oscillator strengths of both resonance transitions of Sr + a value of about unity.

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 ...

On the Accuracy of Oscillator Strengths
1991It is important to investigate whether non—relativistic errors in calculated oscillator strengths and related atomic data are large enough to obscure corrections applied in relativistic calculations. The magnitude such errors is however difficult to estimate.

On the MgH oscillator strengths
Journal of Astrophysics and Astronomy, 1981The theoretical estimates of the oscillator strengths by Kirby, Saxon and Liu (1979) for theA II2 — XΣ2 system of the MgH molecule are compared with the solar photospheric results. It is found that the two results are in reasonable agreement.

The oscillator strength in atomic absorption spectroscopy
Spectrochimica Acta Part B: Atomic Spectroscopy, 1994Abstract The role of the oscillator strength, f, in the theory of atomic absorption is investigated. For a pure natural broadened absorption line, the peak absorption coefficient αo is independent of the oscillator strength. The peak absorption coefficient becomes dependent on f only through additional broadening processes such as Doppler or ...

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.
