Precision measurement of relative oscillator strengths - V. Comparison of oscillator strengths of Fe I transitions from levels a5 F1-5 (0.86-1.01 eV) and those from a5 D0-4 (0.00-0.12 eV)

Semiclassical calculation of oscillator-strengths

2014 Because they play a fundamental role in the calculation of bound electron stoppingpowers, photon mean free paths and electron impact-excitation cross-sections, there is a need for a convenient method to calculate oscillator strengths for highly charged ions. In this paper we describe a simple semiclassical approximation for electron matrix-elements and oscillator strengths. The method is t...

Oscillator strengths with pseudopotentials

The time-dependent local-density approximation (TDLDA) is shown to remain accurate in describing the atomic response of group IB elements under the additional approximation of using pseudopotentials to treat the effects of core electrons. This extends the work of Zangwill and Soven who showed the utility of the all-electron TDLDA in the atomic response problem.

Oscillator Strengths of Astrophysical Interest

Oscillator strengths for transitions of astrophysical importance in SIII

Relativistic Quantum Defect Orbital (RQDO) calculations, with and without explict account for core-valence correlation, have been performed on dipole-allowed transitions between the levels belonging to the 3s2 3p2, 3s2 3p nd (n = 3, 4, 5), 3s2 3p ns (n = 4, 5) and 3s2 3p 4p configurations of the Si-like ion SIII in the LS-coupling scheme. The present oscillator strengths, which are of considera...
