Abstract:
Energies of the lowest 157 levels belonging to the
(1s2) 2s 22p6, 2s 22p 53l, 2s 22p 54l, 2s 22p 55l,
2s2p 63l, 2s2p 64l and 2s2p 65l configurations of Fe XVII have
been calculated using the GRASP code of Dyall et al. (1989, Comput.
Phys. Commun., 55, 424). Additionally, radiative rates, oscillator
strengths, and line strengths are calculated for all electric dipole
(E1), magnetic dipole (M1), electric quadrupole (E2), and magnetic
quadrupole (M2) transitions among these levels. Comparisons are made
with the results already available in the literature, and the accuracy
of the data is assessed. Our energy levels are expected to be accurate
to better than 1%, whereas results for other parameters are probably
accurate to better than 20%.
