An approach to atomic structure calculations is described, using recent developments in the pseudo-state/R-matrix method, within the high optimization o †ered by close-coupling. These include the exploitation of the ""QBÏÏ method for systematic resonance analysis, the deÐnition and use of ""core base statesÏÏ for the target, and the incorporation of relativistic e †ects in the Opacity Project codes. A comprehensive set of data is calculated for Ðne-structure bound and continuum states of the form 1s22snl and 1s22pnl (J \ 0e and J \ 1o) up to n \ 10 for the Be-like ion C III, together with electric dipole oscillator strengths.
