Abstract
The coupled integral equations for the system are considered for -wave isobars in states. For phenomenological objectives the equations are made tractable and the subenergy dependence of the isobar amplitudes is organized according to a collection of resolvents. These quantities satisfy coupled integral equations which are solved by means of a basis-function method. Calculations of the resolvents as functions of the subenergy variable are made for total energy GeV. All of the large number of results admit a useful physical parametrization in terms of a sort of complex scattering length. A remarkable sign regularity among the parameters is observed and interpreted.
