The international IRON Project aims to produce accurate cross sections for excitation of ions of Fe and other elements which are crucial in many areas of astrophysics and technology. We have used an R-matrix codefootnote[1]K.A. Berrington, W.B. Eissner and P.H. Norrington 1995, Comp. Phys. Comm. 92 290 for the inelastic scattering of electrons from Be-like Fe XXIII. Here we give preliminary results for collision strengths obtained using an LS coupled target with 54 terms. Our calculation has been done for energies above 85 Ry with respect to the ground term. We compare our data with those of other theoretical calculations. A discussion of how to compute the contribution from high partial waves is presentedfootnote[2]M.C. Chidichimo and K. Rohlf 1996, Z. Phys. D 38 133. We also show how the use of Born limitsfootnote[3]A. Burgess, M.C. Chidichimo and J.A. Tully 1997, J. Phys. B in press together with the graphics program OMEUPSfootnote[4]A. Burgess and J.A. Tully 1992, A&A 254, 436 allows collision strengths at high energies to be estimated without having to do a partial wave expansion. Future work will extend the present calculations to lower energies where the Breit-Pauli Hamiltonian will be used.
