Abstract
The lifetime of the recently discovered emitter Kr was recently found considerably below the lower limit predicted theoretically. This communication addresses this issue.Different separation energy systematics are analyzed and different mechanisms for emission are evaluated. It is found that the most plausible reason for this disagreement is a decay mechanism of Kr, which is not "true " emission, but "transition dynamics" on the borderline between true and sequential decay mechanisms. If this is true, this imposes stringent limits MeV on the ground state energy of Br relative to the Se- threshold.
