Scientific paper

Collision strengths and effective collision strengths are presented for several transitions obtained on the basis of the R-matrix method for lower partial waves and close-coupling, with the omission of exchange terms and Coulomb-Born and Coulomb-Bethe approximations for higher partial waves. Accurate configuration-interaction wave functions are used for the target representation. The resonance structure below the n=2 and n=3 levels is investigated. It is assumed that the magnetic interactions are negligible, and the total orbital and total spin angular momenta are separately conserved; these measures may yield slight errors in the results for some transitions.
