- The gallium spectrum emitted from a hollow cathode has been recorded in the region 500-9800 A. 142 lines have been classified as transitions in Ga II. Energy levels have been derived from the observations, and perturbations within the n = 4 configuration complex are discussed. Besides the previously known mixing between 4s4d and 4p2, it has been found that the structure of 4s4/is strongly affected by interaction with 4p4d. The ionization limit has been determined to 165 465.8 cm-1.

- Spectra emitted from laser-produced plasmas of scandium, titanium, vanadium and chromium have been recorded in the region 270-600 Å, and lines belonging to the 3s-3p and 3p-3d transition arrays in neonlike ions have been identified. The 2p53s, 3p and 3d energy levels have been derived from the observations for Ti XIII and from solar flare lines for Fe XVII. Hartree-Fock calculations and parametric fits have yielded scaling factors for ab initio energy integrals that make it possible to predicts 3s-3p and 3p-3d wavelengths. Observed and predicted wavelengths for the strongest lines in Sc XII, V XIV, Cr XV and Ni XIX are presented.

4s-4p transitions including intercombination lines in Zn-like Zr XI, Nb XII and Mo XIII

Tidskriftsartikel (refereegranskat)abstract
- Energy levels of the configurations 4s4p and 4p2 in zink-like Zr, Nb and Mo have been derived through the identification of spectral lines emitted from laser-produced plasmas. Intercombination lines in the 4s4p-4p2 transition connect the singlet and triplet systems. Wavelengths for spinforbidden and magnetic quadrupole ground term combinations have been derived from the energy levels.
