Atomic Spectroscopy Data
- Atomic Spectra Database
Version 3
- Yu. Ralchenko, F.-C. Jou, D.E. Kelleher, A.E. Kramida, A. Musgrove,
J. Reader, W.L. Wiese, and K. Olsen
- This database contains critically evaluated NIST data for radiative transitions
and energy levels in atoms and atomic ions. Data are included for observed
transitions of 99 elements and energy levels of 57 elements. ASD
contains data on about 950 spectra from about 0.4 Å to 500 µm,
with about 77,000 energy levels and 141,000 lines, 60,000 of which
have transition probabilities.
The database management system has been completely replaced by a relational
database management system. This assures a high level of consistency and
integration of the data, as for example the information on the lines and levels
of an atom. A new version of the interface has been developed. The interface
for the return pages includes direct access to the bibliographic references.
The multiplet-averaged data can be retrieved for arbitrary atoms and ions. An
advanced help system is provided with balloon explanations of various symbols
and quantities.
New graphical features include dynamic transition plots (Grotrian diagrams)
with ability to zoom into particular energy levels and their transitions, and
online generated plots for Saha/Local Thermodynamic Equilibrium (LTE) plasma
emission spectra for arbitrary electron temperature and density. The Grotrian
diagrams interface requires a Java2 plugin (available at
java.sun.com)
for the user's browser. Also plots showing positions of spectral lines from
different ions can be generated online.
- Handbook of Basic Atomic
Spectroscopic Data
- J.E. Sansonetti, W.C. Martin, and S.L. Young
- This handbook provides a selection of the most important and frequently
used atomic spectroscopic data. The compilation includes data for the neutral
and singly-ionized atoms of all elements hydrogen through einsteinium
(Z = 1-99). The wavelengths, intensities, and spectrum
assignments are given in a table for each element, and the data for the
approximately 12,000 lines of all elements are also collected into a finding
list, sorted by wavelength. The energy levels and transition probabilities
(where available) are listed for a total of about 2,400 of the most persistent
lines and we also give a separate table of energy level data for each spectrum.
Details of the atomic weight, isotopic abundance, mass, nuclear spin, and
magnetic moment of each element are also provided.
- Energy Levels of Hydrogen and
Deuterium
- U.D. Jentschura, S. Kotochigova, E.O. Le Bigot, P.J. Mohr, and B.N. Taylor
- This database provides theoretical values of energy levels of hydrogen and
deuterium for principle quantum numbers n = 1 to 200 and all
allowed orbital angular momenta l and total angular
momenta j. The values are based on current knowledge of the
revelant theoretical contributions including relativistic, quantum
electrodynamic, recoil, and nuclear size effects. Contributions that are only
known for low n states have been extrapolated to highly-excited states.
- Ground Levels and
Ionization Energies for the Neutral Atoms
- W.C. Martin, A. Musgrove, and J.E. Sansonetti
- This table gives the principal ionization energies (in eV) for the
neutral atoms from hydrogen (Z=1) through rutherfordium (Z=104).
The spectroscopy notations for the electron configurations and term names
for the ground levels are also included.
- Spectral Data for
the Chandra X-ray Observatory
- L.I. Podobedova, A. Musgrove, D.E. Kelleher, J. Reader, W.L. Wiese
- Tables of critically compiled wavelengths, energy levels, line
classifications, and transition probabilities are given for ionized spectra
of neon (Ne V to Ne VIII), magnesium (Mg V to Mg X),
silicon (Si VI to Si XII), and sulfur (S VIII to S XIV)
in the 20 Å to 170 Å region.
- FLYCHK Collisional-Radiative
Code
- H.-K. Chung, M.H. Chen, R.W. Lee, and Yu. Ralchenko
- Collisional-radiative code FLYCHK calculates atomic level populations,
charge state distributions, and plasma emission spectra
for low-Z to mid-Z elements under non-local thermodynamic
equilibrium (NLTE) conditions.
- SAHA Plasma Population Kinetics
Database
- Yu. Ralchenko
- This database contains benchmark results for simulation of plasma
population kinetics and emission spectra. The data were contributed by the
participants of the 3rd Non-LTE Code Comparison Workshop. The available data
include mean ion charges, ion populations, atomic process rates and other
parameters over a wide range of temperatures and densities for a number of
elements from C to Au.
- NLTE4 Plasma Population Kinetics Database
- Yu. Ralchenko
- This database contains benchmark results for simulation of plasma population kinetics and emission spectra. The data were contributed by the participants of the 4th Non-LTE Code Comparison Workshop. The available data include mean ion charges, ion populations, atomic process rates and other parameters over a wide range of temperatures and densities for C, Ar, Fe, Sn, Xe, and Au.
- Spectrum of Platinum Lamp
for Ultraviolet Spectrograph Calibration
- J.E. Sansonetti, J. Reader, C.J. Sansonetti, and N. Acquista
- An atlas of the spectrum of a platinum/neon hollow-cathode reference
lamp in the region 1130 Å to 4330 Å is given, with the spectral
lines marked and their intensities, wavelengths, and classifications
listed. Graphical figures of the spectrum are included.
- X-ray Transition
Energies
- R.D. Deslattes, E.G. Kessler, Jr., P. Indelicato, L. de Billy, E. Lindroth, and J. Anton
- This X-ray transition table provides the energies and wavelengths for the K and L transitions
connecting energy levels having principal quantum numbers n = 1, 2, 3, and 4.
The elements covered include Z = 10, neon to
Z = 100, fermium. There are
two unique features of this database: (1) all experimental values are on
a scale consistent with the International System of measurement (the SI) and
the numerical values are determined using constants from the Recommended Values of the Fundamental
Physical Constants: 1998 and (2) accurate theoretical estimates are
included for all transitions.
