AbstractResonance states govern a large variety of molecular processes. Thus, controlling the decay process of a given resonance implies to control the molecular process mediated by that resonance state. In general it is desirable to preserve the inherent dynamics of the system, which implies to work in weak-field (one photon) conditions. In these conditions quantum interference becomes a very useful tool in order to exert control, and overlapping resonances are ideal states where interference takes place. The two essential observable properties associated with the decay of a resonance state are its lifetime and the final product fragment state distribution produced upon resonance decay. Schemes to control the lifetime of a single resonance state have been developed for overlapping resonances in the weak-field limit [1-3]. Control strategies to modify the product fragment state distributions produced by the decay of a superposition of overlapping resonances have also been proposed [4-6]. Such a control was achieved both on the transient [4] and on the long-time, asymptotic fragment state distribution [6]. A unified theory based on a single scheme to control both the resonance lifetime and the fragment distribution produced after resonance decay is proposed and presented [7].
