Energies of the 700 lowest levels in Fe XX have been obtained using the
multiconfiguration Dirac-Fock method. Configuration interaction method on the
basis set of transformed radial orbitals with variable parameters taking into
account relativistic corrections in the Breit-Pauli approximation was used to
crosscheck our presented results. Transition probabilities, oscillator and
line strengths are presented for electric dipole (E1), electric quadrupole
(E2) and magnetic dipole (M1) transitions among these levels. The total
radiative transition probabilities from each level are also provided. Results
are compared with data compiled by NIST and with other theoretical work.
