Atomic data and spectral line intensities for Ne III
Abstract
Electron impact collision strengths, energy levels, oscillator strengths, and spontaneous radiative decay rates are calculated for Ne III. The configurations used are 2s ^{2}2p ^{4}, 2s2p ^{5}, 2p ^{6}, 2s ^{2}2p ^{3}3s, 2s ^{2}2p ^{3}3p, and 2s ^{2}2p ^{3}3d giving rise to 86 finestructure levels in intermediate coupling. Collision strengths are calculated at five incident energies, 5.2, 10, 15, 20, and 25 Ry. Excitation rate coefficients are calculated as a function of electron temperature by assuming a Maxwellian electron velocity distribution. Using the excitation rate coefficients and the radiative transition rates, statistical equilibrium equations for level populations are solved at electron densities covering the range of 10 ^{8} to 10 ^{14} cm ^{3} at an electron temperature of log T_{e} (K) = 5.0, corresponding to maximum abundance of Ne III. Relative spectral line intensities are calculated.
