Photoionization cross sections and oscillator strengths for Fe
Ab initio calculations are carried out for the photoionization cross sections and oscillator strengths for Fe III in the close-coupling approximation employing the R-matrix method. A 49-state eigenfunction expansion for Fe IV, with states dominated by the ground configuration 3d and the excited configurations 3d 4s and 3d 4p , is employed to ensure an extensive treatment of autoionizing resonan...
متن کاملAtomic data for opacity calculations : XX . Photoionization cross sections and oscillator strengths for Fe 11
Abshnct. Large scale ab initio calculations for the radiative data of Fe II have bcen carried out in lhe close coupling (cc) approximation employing the R-matrix method and a target slate expansion consisting of 83 LS terms of Fe 111. All bound states of Fe II with n< 10 and / <7 are considered. The results include 1301 bound states in LS coupling, oscillator strengths for 35 941 transitions am...
متن کاملOscillator 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 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...
