Abstract : In an earlier work (see AD-636 763) a numerical calculation was made of S wave pseudoscalar meson baryon scattering in a simple broken SU(3) model based on a static vector meson exchange potential and coupled channel Schrodinger equation. In the present work these calculations are extended to finding the location of the poles of the scattering matrix in the multisheeted complex energy plane and the motion of these poles as the strength of the potential is varied. Particular attention is paid to the behavior of the poles when the potential strength is such that there is a resonance close to a threshold. (Author)
