Abstract
The lifetime of a long-lived x-ray emitter produced in foil excitation of chlorine beams between 40.3 and 57.5 MeV has been measured to be 280±25 nsec. The measured photon energy of the transition indicates that it arises from the decay in heliumlike chlorine. The observed lifetime is shorter than the theoretical lifetime of 381 nsec predicted for this transition.
