We report in this paper the computation of accurate total collision strengths and effective collision strengths for electron-impact excitation of FeII, using the parallel R-matrix program PRMAT. Target states corresponding to the 3d64s, 3d7, 3d64p an

Effective collision strengths are presented for the Fe-peak element Fe III at electron temperatures (Te in degrees Kelvin) in the range 2 × 103 to 1 × 106. Forbidden transitions results are given between the 3d6, 3d54s, and the 3d54p manifolds appl

In order to investigate the existence and effect of broad, 'two-particle-one-hole' resonance structure in low-energy electron scattering from the Fe-peak ion Ni V, the parallel R-matrix computer package, PRMAT, has been employed to evaluate the colli

We present total effective collision strengths for electron-impact excitation of Fe II, calculated using the parallel R-matrix program PRMAT, for all sextet to quartet forbidden transitions among the lowest 113 LS states formed from the 3d64s, 3d7, 3

We describe a successful implementation of a version of the R-matrix method reformulated with physical and numerical parallelization in mind, and apply it, as a prototype example, to the calculation of optically forbidden electron-impact excitations
