title: On the Competition between Predissociation and Direct Dissociation in Deuterium Chloride Ions (DCl(+)).
abstract: The competition between direct dissociation and predissociation in DCl(+) ions prepared in the A(2)Σ(+) state has been investigated numerically by solving the time dependent Schrödinger equation. This work concentrates on the rovibronic states (vA;NA) with vA = 8 and NA = 60-65, which are close to the top of a centrifugal barrier. We find that the relative yield of D(+) (by direct dissociation) and Cl(+) (by predissociation) strongly depends on the excitation frequency, intensity, and duration. Investigation of the time dependence of the product yields provides evidence for significant multichannel interactions.
