Lifetime of the $3p{}^2{P}_{3/2}$ level in sodiumlike bromine (Br XXV)

Using the beam-foil spectroscopy technique, we have measured the decay time of the $3p{}^2{P}_{3/2}$ level in sodiumlike bromine. The results, using an arbitrarily normalized decay curves analysis, are in good agreement with the most recent theoretical calculations. They also confirm an earlier experimental result in sodiumlike krypton, suggesting that some previous measurements of the lifetimes of $3p{}^2{P}_{3/2}$ states of nearby isoelectronic ions are too high.
