Abstract

A Fourier transform spectrometer was used to obtain high-resolution spectra of a ²³⁴UI₄/²³⁸UI₄ electrodeless discharge lamp. Over 2000 uranium isotope shifts were measured in the visible and near-infrared regions. Level isotope shifts were determined by least squares for 183 odd and 518 even levels of U i with an overall standard deviation of 0.0036 cm⁻¹.
