Kramida A - J Res Natl Inst Stand Technol (2013)

Bottom Line: Uncertainties of the energy level values have been reduced by an order of magnitude.An improved value of the ionization limit of In II has been determined by fitting quantum-defect and polarization formulas for several series of levels.The hyperfine structure interval in the 5s (2)S ground state of In III has been determined from the measurements of the 5sng and 5snh series in In II.

ABSTRACT
A comprehensive list of the best measured wavelengths in the In II spectrum has been compiled. Uncertainties of the wavelength measurements have been analyzed, and existing inconsistencies have been resolved. An optimized set of fine-structure energy levels that fits all observed wavelengths has been derived. Uncertainties of the energy level values have been reduced by an order of magnitude. An improved value of the ionization limit of In II has been determined by fitting quantum-defect and polarization formulas for several series of levels. Intensities of lines observed by different authors have been analyzed and converted to a uniform scale. A set of recommended values of radiative transition rates has been critically compiled, and uncertainties of these rates have been estimated. The hyperfine structure interval in the 5s (2)S ground state of In III has been determined from the measurements of the 5sng and 5snh series in In II.

Verification of linearity of the corrected intensity scale for the observations of Paschen and Campbell [2]. The solid curve is a linear fit to the data points. Its slope is close to one, and it nearly crosses the (0, 0) point.

f3-jres.118.004: Verification of linearity of the corrected intensity scale for the observations of Paschen and Campbell [2]. The solid curve is a linear fit to the data points. Its slope is close to one, and it nearly crosses the (0, 0) point.

Mentions: To verify that the non-linearity was correctly removed from the intensity values, the logarithm of the calculated intensities is plotted against the corrected observed intensities in Fig. 3. In this plot, the wavelength dependence was removed from all observations.
