The lifetime of the long-lived 5d(2)D(5/2) level in Ba-138(+) ions was measured in trapped single ions and small ion crystals using continuous quantum jump spectroscopy. We find tau(D5/2) = 25.6(0.5) s, significantly below previously reported values. We have verified our result by exploiting camera images of the stored ions, which enabled monitoring the cleanliness and sufficiently low temperature of the ion samples, and investigating common systematic effects.
