Abstract
The spectrum of Eu iii obtained with a 6 A sliding-spark discharge has been measured from 2000 Å to 9000 Å. Of the 890 spectral lines observed, one-third are classified in an energy-level scheme consisting of 104 excited levels. These belong to the 4f7 configuration and to the 4f6(7F)5d, 4f6(7F)6s, and 4f6(7F)6p subconfigurations. Except for 4f7, calculations of these configurations with least-squares-adjusted parameters were carried out. A reasonably suitable truncation for the energy matrices of each configuration was found.
