[en] Absolute emission coefficient measurements on arc-generated singly ionized uranium (UII) in local thermodynamic equilibrium are described for a wavelength bandwidth of 1050 to 6000 A. Plasma temperature and uranium partial pressure at the arc centerline were approximately 8000⁰K and 0.01 atm, respectively. The arc emission data compare favorably with experimental results obtained from UF₆ discharges, once allowance is made for the effects of cold-layer UF₆ photoabsorption on uranium plasma emission. Observed variation in the emission coefficient is well correlated with a composite of calculated oscillator-strength distribution for selected UII and UIII transition arrays. The theoretical treatment is based on a modified Hartree--Fock method for calculating the appropriate radial wave functions. Slater--Condon theory provides a detailed calculation of energy-level structures for both the upper and lower configuration of each transition array computed. However, the number of terms were truncated, when necessary, to accommodate size limitations of the matrices involved. With this theoretical approach, predictions are also offered as to the location of strong emission features for a hypothetical plasma dominated by doubly and triply ionized uranium. It is suggested that the capability now exists to predict successfully the location of major emission features of uranium and other complex systems for a substantial range of ionization stages
