Abstract

We provide new measurements of wavenumbers and line identifications of 10100 UI and UII near-infrared (NIR) emission lines between 2500 cm−1 and 12000 cm−1 (4000 nm to 850 nm) using archival FTS spectra from the National Solar Observatory (NSO). This line list includes isolated uranium lines in the Y, J, H, K, and L bands (0.9 to 1.1 μm, 1.2 to 1.35 μm, 1.5 to 1.65 μm, 2.0 to 2.4 μm, and 3.0 to 4.0 μm, respectively), and provides six times as many calibration lines as thorium in the NIR spectral range. The line lists we provide enable inexpensive, commercially-available uranium hollow-cathode lamps to be used for high-precision wavelength calibration of existing and future high-resolution NIR spectrographs.
