  • Atom - NORAD-Atomic-Data Access metric charts
  • Introduction:
  • Brief Description of NORAD-Atomic-Data database:
  • The on-line NORAD-Atomic-Data based at the Ohio State University contains large amount calculated atomic data relevant to various radiative and collisional atomic processes, such as, excitation of energies, photoionization, electron-ion recombination, radiative transitions, lifetimes, etc relevant to astrophysical and laboratory plasmas. They are obtained mainly from large scale R-MATRIX calculations and some from atomic structure program SUPERSTRUCTURE carried out at the Ohio Supercomputer Center (OSC) by Nahar et al

  • Each datafile contains the reference of the data. The referenced papers are available at Research Publications

  • Contents of Atomic Data files are:
    - i) Energies,
    - ii) Oscillator Strengths, transition probabilities for allowed and forbidden transitions,
    - iii) Photoionization cross sections,
    - iv) Electron-Ion Recombination cross sections and rate coefficients,
    - v) Lifetimes,

  • Recent enhancements are: following additional data are being added to the database

    - vi) spectral points with transition energies (independent of plasma environment)
    - vii) Collision Strengths (OMEGA) (limited data),
    - viii) Experimental energies and lines,
    - ix) Experimental photoionization cross sections
    - x) Interactive Line-ratios calculation for astrophysical spectra using NORAD-Atomic-Data

    A significant part of the atomic data were obtained under the two international collaborations,

  • the Opacity Project (OP), and
  • the Iron Project (IP).
    - 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.

  • Current data at NORAD-Atomic-Data:

    The database includes:
    -Radiative atomic data for:
    163 [99 in Table 1 with Z=1-28 + 73 in Table 2 with Z > 28] atoms & ions

    -Atomic collision data for:
    1 ion (Ca IV) in Table 3

    -Measured line and energy data
    8 ions (heavy elements) in Table 4

    -Measured Photoionization Cross Sections
    8 ions in Table 5

    Total number of atomic species: 180

    - additional data for 42 ions are under process
    - New data are added with publications. SNN would appreciate acknowledgement of usage of NORAD-Atomic-Data web-page in your publications
    - NORAD-Atomic-Data are either new/updated over those from the original the Opacity Project (OP) and Iron Project (IP) at

  • TOPbase,
  • TIPbase
    - You may be interested in the monochromatice opacity data and codes from the OP and IP at OPserver at Ohio Supercomputer Center site:
  • OPserver

    - 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. They can be connected to the numerical identification codes given in cross section and rate coefficient files.

    Notation Description:

    Explanation of notation in "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
