Electron impact excitations and de-excitation rate coefficients of the excited ion Fe XVI are calculated according to the analytical formulas of Vriens and Smeets. A simple modification has been made by substituting effective quantum numbers in Vriens formulas to be applicable for the ion under consideration. The energy levels and transition probabilities have been calculated using the multiconfiguration Hartree-Fock (MCHF) method with Breit-Pauli relativistic correction (CF.Fischer's ATSP computer package) in which the monopole and the quadrupole transitions have been introduced in the calculations in addition to the dipole transitions. Level population densities are then calculated by solving the coupled rate equations involving the 54 levels 1i2i2p6nl, where n=3-8 and 1=0,1,2,3,4,5. Positive gain coefficients are displayedfor the transitions 5p(2P1/1/2)?4d(2D3/2), 5p(2p3/2) ? 4d(2D32) and 5p(2p3/2) ? 4d(2D5/2) at three selected electron temperatures namely 1/4, 1/2 and 3/4 the ionization potential.
