Oscillator strengths for AsI-III

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 for neutral selenium and tellurium

Oscillator strengths for excitations of neutral selenium and tellurium from the ground state are calculated using a semiempirical analytic independent-particle-model. The results are compared to experimental and theoretical data.

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 FOR ULTRAVIOLET TRANSITIONS IN Cl ii AND Cl iii

Oscillator strengths for transitions in Cl ii and iii are derived from lifetimes and branching fractions measured with beam-foil techniques. The focus is on the multiplets at 10718 in Cl ii and 10118 in Cl iiiwhose lines are seen in spectra acquired with the Far Ultraviolet Spectroscopic Explorer. These data represent the first complete set of experimental f-values for the lines in the multiple...
