Theoretical calculations of electron impact single and double ionization cross sections for ground state Fe atoms have been performed in the binary encounter approximation(BEA) in the energy region ranging from threshold to 1250 eV and 1200eV respectively. The accurate expression for αΔE (cross section for energy transfer ΔE) including exchange and interference as given by Vriens and Hartree –Fock velocity distributions for the target electrons have been used throughout the calculations.
