✦ Synopsis

TIMEDEL takes K-matrices from a scattering calculation, either read from a file or calculated on a dynamically adjusted grid, and calculates the time-delay matrix. This is then diagonalized to find the longest time-delay experienced by the scattering particle. The branching ratio of decay into the open channels is also found and optionally output. A resonance shows up as a characteristic Lorentzian form in the time-delay and the program searches the time-delay for maxima. It determines, from the overlap of adjacent resonances, whether each resonance should be fitted on its own or jointly with one or more other resonances. It performs the fitting and outputs the positions and widths of the resonances. (
