A method of extracting resonance parameters from scattering data is outlined for
scattering that involves Coulomb interactions. This is done for single-channel
scattering, as well as multi-channel scattering. Within the ...
A new parametrization of the multi-channel S
-matrix is used to fit scattering data and then to locate the resonances as its poles. The S
-matrix is written in terms of the corresponding “in” and “out” Jost ...
