摘要：

The R-matrix method is used to calculate electron impact collision strengths of chlorine-like Fe x for transitions among the 14 lowest LS states, i.e., up to the 3s(3)3p(4)(P-3)3d state. Configuration interaction wave functions are used to represent the target states included in the R-matrix expansion. Effective collision strengths are calculated among the fine structure levels of the ground state and from the ground to excited states by employing a transformation of the LS-coupled reactance matrices, and by assuming a Maxwellian velocity distribution for the incident electron. The results are tabulated for electron temperatures in the range log T-e = 4.0 to log T-e = 6.4 with T-e expressed in kelvins.
