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.
متن کاملAtomic Oscillator Strengths in the Vacuum Ultraviolet
We have developed techniques to measure branching fractions in the vacuum ultraviolet using diffraction grating spectroscopy and phosphor image plates as detectors. These techniques have been used to measure branching fractions in Fe II that give prominent emission lines in astrophysical objects.
متن کاملWeighted Oscillator Strengths and Lifetimes for the Neutral Oxygen Spectrum, O I
The weighted oscillator strengths (gf) and the lifetimes for O I presented in this work were obtained in a multicon guration Hartree-Fock relativistic (HFR) approach. In this calculation, the electrostatic parameters were optimized by a least-squares procedure, in order to improve the adjustment to experimental energy levels. This method produces gf-values that are in better agreement with inte...
متن کاملOscillator 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.
متن کاملSemiclassical 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...
