The lifetime of the 2 [sup 3][ital P][sub 2] level in heliumlike krypton has been measured by an alternative method involving the use of a two-foil target. The experiment demonstrates the potential of this method which allows the standard beam-foil time-of-flight technique to be extended to shorter lifetimes. We measured a lifetime of 9.5[plus minus]0.9 ps, which is in reasonable agreement with current theoretical calculations.
