Electron excitation collision strengths for fine-structure transitions
3s23p5-3s3p6,
3s23p5-3s23p43d and 3s3p6-3s23p43d
in Fe x,
are calculated using a 180-level Breit-Pauli R-matrix calculation
containing the above levels together with those from
3s3p53d and 3s23p33d2 configurations.
The collision strength is averaged over a Maxwellian velocity distribution to
obtain the effective fine-structure
collision strengths as a function of electron temperature
from 
.
We show that low-energy resonances enhance the effective collision strength,
with significant effects on level populations.
