Energy levels and spectral lines of singly ionized manganese (Mn II)



Alexander Kramida, Jean E. Sansonetti


This compilation revises the previously recommended list of energy levels of singly ionized manganese (Mn II) 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 a hundred high-precision wavelengths determined by laser spectroscopy and Fourier transform techniques. Uncertainties of 63 % of energy levels and 74 % of Ritz wavelengths are reduced by a factor of three on average.
