Abstract
Emission of x rays from foil-excited sulphur beams at 40, 50, and 55 MeV has been observed. Lifetimes of the state in helium-like and the state in lithium-like sulphur, which decay partially by magnetic-quadrupole transitions, have been determined. The energies of several transitions to the ground state in two- and three-electron sulphur ions have been determined by using a Doppler-tuned spectrometer and observing the beam both downstream and close to the exciting foil. It is pointed out that the identification of lines in the prompt spectrum of such highly ionized systems in terms of configuration-averaged satellites is inappropriate.
