Energy Levels And Spectral Lines Of Quadruply Ionized Iron (Fe V)
This compilation revises and extends the previously recommended list of energy levels of quadruply ionized iron (Fe V) and provides a comprehensive list of observed spectral lines and transition probabilities in this spectrum. The new level optimization takes into account critically assessed uncertainties of measured wavelengths and includes about 2,000 wavelengths measured with grating spectrographs. For 80 % of energy levels, relative uncertainties have been reduced by a factor of three on average. For 65 % of observed lines, uncertainties of the new Ritz wavelengths are smaller than those of observed wavelengths by a factor of four on average.
