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.
