  We propose a scheme for slowing down decay into a continuum. We make use of a
sequence of ultrashort $2\pi$-pulses applied on an auxiliary transition of the
system so that there is a destructive interference between the two transition
amplitudes - one before the application of the pulse and the other after the
application of the pulse. We give explicit results for a structured continuum.
Our scheme can also inhibit unwanted transitions.
