Introduction:

NORAD-Atomic-Data, the on-line database based at the Ohio State University, presents calculated Atomic Data files are for:

- i) Energies, ii) Oscillator Strengths, iii) Photoionization, iv) Electron-Ion Recombination, v) Lifetimes, vi) Collision Strengths (OMG)

  • Current (July 2016) data are for: 120 [92(1) + 28(2)] atoms & ions

  • New data are added with publications
  • Would appreciate acknowledgement of usage of NORAD-Atomic-Data web-page in your publications - SNN

  • NORAD-Atomic-Data contains large amount data relevant to various atomic processes, such as, excitation of energies, photoionization, electron-ion recombination, radiative transitions, lifetimes, etc. They are obtained mainly from large scale R-matrix calculations carried out at the Ohio Supercomputer Center (OSC) by Nahar et al
  • A significant part of the atomic data were obtained under the two international collaborations, the Opacity Project and the Iron Project. The data sets contain atomic energy levels, photoionization cross sections, recombination cross sections and rate coefficients, oscillator strengths, lifetimes and other transition parameters. It also has collision strengths for electron-impact excitation for a few atomic species. These atomic processes are considered for large number of energy levels, typically going up to n=10 that are needed for complete astrophysical models, diagnostics of astrophysical and laboratory plasma. Hence each ion has significant amount of data.
  • All files are in standard ascii character format for easy downloading and direct application to models. Spectroscopic information for all levels and transitions are provided. The spectroscopic identifications are given mainly in the energy tables. Then can connect easily to the numerical identification codes given in cross section and rate coefficient files.
  • The atomic data are either new/updated over TOPbase, on radiative atomic processes in Astrophysical & Laboratory Plasmas.
  • Some details of the data page are given in the ICAMDATA 2012 presentation "NORAD-Atomic-Data, the on-line database based at the Ohio State University"

  • This page set-up was initiated by Dr. Carlos Allende Prieto at the Steller Astrophysics II conference, Peurto Vallarta, Mexico, April 2007

  • Notation Description:

    Explanation of the "ATOMIC DATA TABLES" (down below):

  • FS -> fine structure, LS -> LS coupling

  • Energies E(LS,FS): E(LS) - LS term energies only, E(FS) - Energies for fine structure levels

  • Oscillator Strength (f), Line Strength (S), Radiative Decay Rate (A): LS - for dipole allowed LS multiplets,
    FORBID - for forbidden transitions, FS - for dipole allowed fine structures transitions (E1: same-spin &
    intercombination), f-exp - fine structure transitions among observed levels

  • Lifetimes: Lifetime - lifetimes of excited levels (with allowed transitions, R-matrix) Lifetime-ss - lifetimes of excited levels (with forbidden and allowed transitions, SUPERSTRUCTURE)

  • 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
    PxPt - partial cross sections for leaving the residual ion in ground and various excited states
    - Description for Photoionization Data

  • 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

  • fPXAC-K: File containing f, photoionization cross section (PX) and absorption coefficient (AC) for K-shell transitions

  • Accuracy Guidelines


  • Atomic Models
