IRON Project VII. FeII radiative transitions
Listed in IVOA Registry (Virtual Observatory)
Table ls.dat contains all LS terms considered in this work and their energy values with complete designation.
Description
Table aij.dat contains f-, S-, and A-values of transitions, both in LS multiplet and in fine structure. For the full designation of the terms in the aij.dat table check the energy table in ls.dat.
A program in Fortran77, prog.f , can read the table in aji.dat and calculate lifetime in seconds from the A-values. The ls.dat and aij.dat present transitions in Fe II (obs-file) among states that have been observed and the calculated energies were replaced by the observed energies to improve the accuracy. The ls2.dat and aij2.dat files (cal-file) contains transitions among the rest of the calculated energy states and all the transition energies are calculated ones.

Hence the two files, one with observed energies (obs-file) and one with calculated energies (cal-file) are complement to each other with no common transitions. The uncertainties of the transition probabilities in cat-files, are expected to be higher than those in the obs-file as the observed energies are more accurate in general than the calculated ones. The transition energy, EDIFF, in cal-file is written by one more significant digit compared to the obs-file with observed energies.
Total data: Number of bound states: Total number of octet bound states below threshold (lmx= 7) = 6 Total number of sextet bound states below threshold (lmx= 9) = 205 Total number of quartet bound states below threshold (lmx= 7)= 308 Total number of doublet bound states below threshold (lmx= 7)= 226 Net Total = 745 Total no of LS multiplets using observed energies = 3109 Total no of fjj values with observed energies = 21,589 Total no of LS multiplets using calculated energies = 16164 Total no of fjj values with calculated energies = 136330 Total number of f-values using observed and calculated transition energies = 157,919
