PARTIAL WIDTHS AND TIME-DEPENDENT DISSOCIATION DYNAMICS BY THE OPTICAL-POTENTIAL METHOD

A procedure to obtain partial widths and branching ratios for half and full collision experiments is developed by using square-integrable wave functions in the framework of the optical potential theory. Stable and precise results are obtained with the two-channel Noro-Taylor model Hamiltonian by calculating the asymptotic quantum flows. This paper discusses the relationships between the long-time limit relaxation induced by the resonance states and the preliminary stage of the dissociation process and shows that, when a simplified scheme is used, parameters as (i) the time at which the flows produced by the resonance are analyzed, (ii) the radial points where this analysis is made, or (iii) the norm of the resonance state, cannot be independently fixed.
