Electron impact collision strengths and spontaneous radiative decay rates are calculated for the Ne-like ion Fe XVII. The data pertain to the 37 levels of the configurations 2s[sup 2]2p[sup 6], 2s[sup 2]2p[sup 5]3s, 2s[sup 2]2p[sup 5]3p, 2s[sup 2]2p[sup 5]3d, 2s2[sup 6]3s, 2s2p[sup 6]3p, and 2s2p[sup 6]3d. Collision strengths are calculated at five energies. In Rydberg units these energies are 76.83, 91.53, 120.93, 179.73, and 253.23. Spectral line intensities are calculated for all transitions with intensities within two orders of magnitude of the most intense line in each ion. These are obtained by computing the excitation rate coefficients (cm[sup 3] s[sup [minus]1]), that is, the collision strengths integrated over a Maxwellian electron distribution, and then solving the equations of detailed balance for the populations of the 37 energy levels, assuming a collisional excitation model. The level populations are computed for several electron densities and are also given in this paper. 17 refs., 4 tabs.
