The Iron Project (IP) [93H1] is mostly devoted to calculating reliable collisional data for all iron ions using the most accurate method, the Breit-Pauli R-matrix closecoupling method, with relativistic fine structure effects. The effective, or maxwellian-averaged, collision strengths tabulated in this section are mostly taken from the collective efforts by the IP. Because this is an on-going endeavor, data for some iron ions by the IP are currently not available. For some of these ions data calculated by the RDW method are also tabulated.

The “–” indicate that the data is not available for those transitions. The order of transitions in Table 2 with respect to the upper and lower levels is mixed, and the initial levels under the column ’Transition’ is not usually the lower one. Therefore care must be exercised in using Eq. (7) or (8) to determine the lower and the upper levels Ei or Ej . 26708). Table 2.
