We have extended the single-centre collisional close-coupling (CCC) method to obtain structure models and calculate positron scattering for atoms containing any number of active electrons with or without an inert core. This was achieved through utilisation of the MULT program developed by Zatsarinny [1] and the Multiconfigural Hartree Fock (MCHF) code developed by Fischer [2]. With this new method we have generated an accurate target structure model for C and calculated several important cross-sections from the e+−C system for energies from threshold to 5000 eV.
