Abstract

The sixth spectrum of uranium (U VI) between 80 and 115 nm is studied by observation of transitions following low-energy electron capture by a U6+-ion beam in a H2 gas target. Emission cross sections of several identified transitions are obtained, the energy dependence investigated, and the spectra compared with the predictions of single-configuration Dirac–Fock (SCDF) calculations. Based on tentative identifications, a Rydberg–Ritz parameterization yields a predicted ionization potential only 0.3% above the SCDF result.
