EXPERIMENTAL TRANSITION-PROBABILITIES OF INTERCOMBINATION TRANSITIONSIN MG-LIKE AND AL-LIKE IONS OF BROMINE

Time-resolved extreme ultraviolet spectra of foil-excited 120-MeV Br i ons have been recorded, using a spectrometer equipped with a position- sensitive detector. The spectra near lambda=20-30 nm were measured at times after excitation of up to 6 ns. Prominent in the delayed spectra were the long-lived decays of the intercombination transitions in the Mg-like Br23+ and Al-like Br22+ ions. The present paper reports on li fetime measurements for intercombination transitions in highly charged bromine ions using such a position-sensitive detector.
