1. General introduction and presentation of the tables
The main purpose of D.E.S.I.R.E.
(DatabasE on SIxth Row Elements) is to provide the
astrophysicists, but also the physicists, with an updated information
concerning the wavelengths, the oscillator strengths, the transition
probabilities and the radiative lifetimes of neutral, singly or
multiply ionized elements belonging to the sixth row of the periodic table.
In our compilation, the spectra are classified in order of increasing
Z-values and, for a given Z, according to the ionization degree.
Database of radiative transitions.
For each line in a particular spectrum,
the tables show, respectively:
- the wavelength (in A) deduced from the experimental energy levels.
These wavelengths are given in air above 2000 A and in vacuum below that limit;
- the lower level of the transition represented by its experimental
value (in cm-1), its parity ((e) for even and (o) for odd)
and its J-value.
- the upper level of the transition presented in the same way as
the lower level;
- the calculated oscillator strength, log gf, where g=2J+1 is
the statistical weight of the lower level of the transition.
More details about the computational procedure are given in the
different publications listed below. Only transitions
for which log gf > -4.0 are reported in the tables.
For some ions, experimental oscillator strengths or normalized oscillator
strengths using measured lifetimes are given. In these
cases, "EXPT" or "NORM" appears in the last column of the tables;
- the calculated weighted transition probability, gA in s-1, where
g=2J+1 is the statistical weight of the upper level of the transition.
For some ions, experimental gA-values or normalized gA-values using
measured lifetimes are given. In these cases, "EXPT" or "NORM"
appears in the last column of the tables;
Database of Landé g-factors.
For each experimental level, the tables give the calculated g-factor obtained
in our work and the measured value when available.
