- Spectral studies following electron capture in slow ion-atom collisions are reported for the collision systems Kr(q+) + He (q = 7, 8, 9) at 10 keV/q. The work introduces part of the spectroscopy program which is beginning at the University of Uppsala ECR ion source facility. In particular a search was made for the 3d(10)4p2P-3d(9)4S(2)2D transitions in Cu-like Kr. This multiplet was found to give transitions with wavelengths 198.56, 194.65 and 190.97 angstrom for the 3/2-5/2, 3/2-3/2 and 1/2-3/2 components respectively.

- By means of the beam-foil method, 74 new lines have been identified as combinations between the core-excited 2p5 3s3p, 3s3d and 3p2 configurations in Na-like sulphur, chlorine, argon and titanium. Relative energies have been determined for most of the quartet levels in S, Cl and Ar with an internal uncertainty of less than 25 cm−1. We also report the first observation in the isoelectronic sequence of Δn = 0, n = 3 transitions from the quasi-metastable 2p5 3p2(3P) 2D5/2 level. The identifications are supported by isoelectronic studies and comparisons with theoretical results obtained in superposition-of-configuration calculations including continuum channels.
