     Overview: Results are from a 90 level intermediate coupling frame
               transformation R-matrix calculation including resonance
               effects and radiation damping for lithium-like argon up
               to the n=3 shell, including all doubly excitied states
               with the exception of 1s3l3l' states.

                 Inner-shll processes of Li- and Be-like Fe

     Level energies: The level energies are theoretical, computed by
                     R-matrix codes from AUTOSTRUCTURE radial wavefunctions. 
                     They have not been altered to best theoretical values.

     Transition Probabilities: These are theoretical, computed by
                               AUTOSTRUCTURE. They include electric
                               dipole, electric quadropole and magnetic
                               dipole values.  Note that the dipole
                               A-values may show slight inconsistencies 
                               (no more than a few percent) with the line
                               strengths given in the final column. The
                               A-values here were optimised for singly 
                               excited states while the line strengths
                               used for extrapolation were optimised for
                               the doubly excited states.

     Rate coefficients: Calculated using R-matrix by C P Ballance in a
                        method paralleling that of the Fe+23 calculation
                        presented in the referenced paper.

                        Detailed attention has been given to the high
                        energy behaviour of the collision strengths as
                        they approach their limiting values, calculated
                        by AUTOSTRUCTURE.  At low energies, the rolling
                        forest of resonance structure was resolved
                        sufficiently to calculate rate coefficients down
                        to 5E4 K. For more details see the referenced
                        paper. Errors of around 20% are expected for the
                        5E4--1E8 temperature range with lesser errors
                        for some transitions (notably the dipoles). Data
                        above this range should be treated as unreliable
                        but preferable to extrapolation of the effective
                        collision strength as a constant.

     Note: Should this data be used, the authors (Ballance et al) request 
           a reference to the above paper and not just a generic ADAS
