Abstract:
A new R-matrix calculation of rate coefficients for electron
collisional excitation of Fe XIII is presented and compared to recent
calculations of comparable complexity. At temperatures at which
Fe12+ is typically found in the solar corona, the present results,
which use the intermediate coupling frame transformation method, show
significant differences compared to some earlier work. We use a large
configuration interaction calculation with extensive correlation to
assess the accuracy of our and earlier workers' scattering targets.
