Description:
Energy levels and the corresponding transition probabilities as well
as oscillator strengths and line strengths for allowed (E1) and
forbidden (E2, M1) transitions among the lowest 407 levels of
boron-like Fe XXII are presented. Calculations were performed using
the multiconfigurational Dirac-Fock GRASP code.
