Electron-impact excitation of Sc II: collision strengths and effective collision strengths for fine-structure transitions

Accurate fine-structure atomic data for the Fe-peak elements are essential for interpreting astronomical spectra. There is a severe paucity of data available for Sc II, highlighted by the fact that no collision strengths are readily available for this ion. We present electron-impact excitation collision strengths and Maxwellian averaged effective collision strengths for Sc II. The collision str...

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...

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...

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.
