Abstract:
Collision strengths for transitions among the lowest 48 fine-structure
levels belonging to the (1s22s22p6) 3s23p4, 3s3p5,
3s23p33d and 3p6 configurations of Fe XI have been calculated
using the Dirac Atomic R-matrix Code (DARC) of Norrington & Grant
(2003, Comput. Phys. Commun., in prep.). Results are tabulated at
energies above thresholds in the range 10≤E≤100Ry, although
resonances have been resolved in a fine energy mesh in the thresholds
region. Effective collision strengths, obtained after integrating the
collision strengths over a Maxwellian distribution of electron
velocities, are also tabulated over a wide electron temperature range
below 5x106K. Comparisons with other available results are made, and
the accuracy of the present data is assessed.
