Chlorine Atomic Data Sets

The following tables have the link to the compressed files of data sets for each ionization stage and the list of non-relativistic configuration. The numbers of fine-structure levels, collisional and radiative transitions are listed as well.

Each compressed file contains 4 files per ion stage YY (YY=1 for neutral atom) of element XX (XX=17 for chlorine) :

struct.XXYY: fine-structure level and oscillator strength [GF] data
eielev.XXYY: electron-impact excitation data [CE]
ionlev.XXYY: photo-ionization [PI] and collisional-ionization [CI] data (using scaled-hydrogenic approach)
dwilev.XXYY: distorted-wave collisional ionization [DW] data from the ground level of that ion stage

Note that for ionization, a logarithmic mesh in energy is used using energy threshold units, where a "threshold unit" is the incident electron energy divided by the ionization threshold. The cross sections are given for 21 energy points, on a log mesh from 1.01 to 100 threshold units.
For excitation this is a little different. Still a log mesh, but now on the final electron energy; and also only 9 points are given. The final-energy mesh is chosen such that the initial and final values are approximately 0.01 and 9.0, respectively, times the largest transition energy to be considered for a given ion stage. This choice ensures that our method for generating the excitation cross sections is robust enough to handle the broad range of excitation transitions that can occur within a given ion stage.
