Abstract

The spectrum of doubly ionized gadolinium was photographed and measured over the region 1900–12 000 Å. The following transitions involving 18 levels and 42 lines were classified: 4f7(8S7/2)6s–6p and 4f7(8S7/2)5d–6p. The Coulombic and spin–orbit matrix elements of the f7(8S7/2)l states were evaluated and the energy levels calculated. Close agreement was obtained between the calculated and experimental values. These calculations indicate that the 4f7(8S7/2)6p states are close to J1j coupling while those of 4f7(8S7/2)5d are close to LS coupling.
