Electron-impact excitation cross sections for Fe{sup 16+} in the configuration-average distorted-wave approximation
- Department of Physics, Auburn University, Auburn, Alabama 36849 (United States)
Electron-impact excitation cross sections for the 2p{sup 6}{yields}2p{sup 5}3l transitions in Fe{sup 16+} are calculated in a configuration-average distorted-wave approximation. Resonant-excitation contributions from the 2p{sup 5}3pnl{sup '}, 2p{sup 5}3dnl{sup '}, and 2p{sup 5}4lnl{sup '} series are included in the isolated resonance approximation. The accuracy of the distorted-wave calculations is determined by comparison with previous 139 level resolved (n{<=}5) fully relativistic R-matrix calculations. Excellent agreement is found between the configuration-average distorted-wave and R-matrix total rate coefficients for the strong 2p{sup 6}{yields}2p{sup 5}3p and 2p{sup 6}{yields}2p{sup 5}3d transitions, while differences found for the relatively weak 2p{sup 6}{yields}2p{sup 5}3s transition are mainly attributed to close-coupling effects.
