Abstract Besides the prompt x-ray emission of Ar-ions, the metastable decay of the heliumlike3 P 2- and the lithiumlike4 P 5/2-levels of highly ionized Ar16+ and Ar15+ atoms has been observed in a foil-excited beam using a flat-crystal spectrometer. Due to the highx-ray energy resolution of the spectrometer the two3 P 2 →1 S 0 and4 P 5/2 →2 S 1/2 transitions could be resolved. The experiment yielded (3128 ±2) eV for the3P2 → and (3091 ± 2)eV for the4 P 5/2 →2 S 1/2 transition energy respectively. Using a time of flight technique the lifetimes of the3 P 2- and the4 P 5/2-states were determined to be (1.44 ±0.09)ns and (0.66 ± 0.05) ns.
