In the framework of the IRON Project we have performed new, fully quantum mechanical atomic calculations for the Fexii (Fe(11+) ) coronal ion. Energy levels, oscillator strengths and spontaneous decay transition probabilities have been computed by including extensive configuration interaction (CI) and relativistic effects in the solution of the atomic structure problem. The R-matrix approach has been employed to solve the electron scattering problem and generate a new set of collisional atomic data. Results are discussed for the ten fine-structure forbidden transitions in the 3s(23p^3) ground configuration of Fexii, and compared with previous calculations.
