Abstract:
Collision strengths for 4005 transitions among the lowest 90 levels of
the (1s22s22p6) 3s23p5, 3s3p6, 3s23p43d, 3s3p53d and
3s23p33d2 configurations of Fe X have been calculated using the
Dirac Atomic R-matrix Code (DARC) of Norrington & Grant (2005, Comput.
Phys. Commun. , in prep.), over a wide energy range up to 210Ryd.
Resonances have been resolved in the threshold region, and effective
collision strengths have been obtained over a wide temperature range
up to 107K. The present calculations should represent a significant
improvement (in both range and accuracy) over the earlier available
results of Bhatia & Doschek (1995, At. Data Nucl. Data Tables, 60,
97), Tayal (2001ApJS..132..117T 2001ApJS..132..117T) and Pelan & Berrington
(2001A&A...365..258P 2001A&A...365..258P). Based on several comparisons, the accuracy of
our data is assessed to be better than 20%, for a majority of
transitions.
