Kramida 2010 | Most of the given level values are essentially experimental ones. More accurate theoretical data on fine-structure energy levels and transitions between them can be obtained in the NIST Database of Energy Levels of Hydrogen and Deuterium. The levels designated only by a principal quantum number n in the configuration column represent centers of groups of all fine-structure levels having the given n. Their values were derived from line series observed in emission from solar corona and are relevant only for this type of observations. Uncertainties of the level values vary between 3 and 23 in the units of the last given decimal place. The level values in square brackets were obtained by interpolation or extrapolation of experimental fine-structure intervals or by fitting the Ritz-type formulas along series of levels. The level values in parentheses were derived from the theoretical values in the NIST Database of Energy Levels of Hydrogen and Deuterium by adding to them calculated off-diagonal magnetic-dipole hyperfine shifts. | Literature on H I Energy Levels |
