Nahar OSU Radiative Atomic Data - NORAD:
Atomic Data Files for - Energies, Radiative Transitions, Photoionization, Electron-Ion Recombination - calculated by Nahar et al, Astrophysics, Ohio State U. (in progess)
  • Would appreciate acknowledging the usage of NORAD web-page in your publications - SNN

    • Explanation of "Atomic Data Table" down below (see Accuracy Guidelines):
  • FS -> fine structure, LS -> LS coupling
  • Energy LS Terms & FS Levels : Energies with spectroscopic designations
  • Oscillator Strength (f), Line Strength (S), Radiative Decay Rate (A): LS - Dipole allowed LS multiplets,
    FORBID - Forbidden transitions, FS - Dipole Allowed fine structures transitions (E1: same-spin &
    intercombination), f-exp - fine structure transitions among observed levels
  • Photoionization (PX): Gd - total photoionization cross sections for the ground state
    Total - total photoionization cross sections leaving the core ion in various core states
    Partial - partial photoionization cross sections leaving the core ion in the ground state
  • Electron-Ion Recombination: RRC - Recombination Rate Coefficients with T (K) for levels & summed total
    OMRX - Total recombination collision strength, cross sections, & rates with photoelectron energies
