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.Keywords
