     The above effective collision strengths for W^46+ were determined
     from a fully relativistic R-matrix calculation that included the
     effects of radiation damping.  The energy levels and radiative rates
     (electric dipole and quadrupole and magnetic dipole and quadrupole)
     were determined from a Dirac-Fock calculation using GRASP.  The
     effective collision strengths for all transitions between the 115
     levels included in the calculation were determined using our parallel
     suite of Dirac R-matrix programs.

     All JPI partial waves from J = 0.5 to 35.5 were included in the R-matrix
     scattering calculation.  The collision strengths for this range of
     partial waves was then topped up.  The size of the continuum basis was
     25, which allowed us to determine collision strengths up to an energy
     of 1200 Ryd.  The size of the R-matrix box was 2.0 au.  In the resonance
     region (for all JPI partial waves from J = 0.5 to 15.5), we employed an
     energy-mesh spacing of 9.4x10^-4 Ryd, for a total of 102400 mesh points.
     In the high-energy region above the last threshold, we employed a total
     of 1000 mesh points for the same range of JPI partial waves.  Finally,
     for the high partial waves from J = 16.5 to 35.5, we employed a total
     of another 1000 energy mesh points in the energy range just below the
     first excitation threshold to 1200. Ryd.

     The numbers in the last column of the above table are the theoretical
     values for the effective collision strengths in the infinite
     temperature limit, as defined in Burgess and Tully Astron. Astrophys.
     254 436 (1992).   For dipole transitions, these were generated from the
     Dirac-Fock calculation, while the non-dipole values were determined
     using a semi-relativistic Thomas-Fermi-Dirac-Amaldi potential
     modified to include the mass-velocity and Darwin terms.
