The atomic structure and x-ray pumping of neonlike Fe xvii have been calculated and modeled under free-electron
laser excitation conditions using the Flexible Atomic Code. Specifically, pumping of the (2p3/23s1/2)2,1,
(2p1/23s1/2)1, (2p3/23d5/2)1, and (2p1/23d3/2)1 levels that connect with the ground state (2s22p6)0 by the so-called
M2, 3G, 3F, 3D, and 3C transitions have been studied. In addition, the spectrum of sodiumlike Fe xvi
has been modeled to account for possible line coincidences with the neonlike spectrum. The calculations include
oscillator strengths, radiative transition probability rates, autoionization rates, non-resonant photoionization
cross sections, and line emissivities.
