# Abstract:

A model of S wave pseudoscalar meson baryon scattering is studied in which the force is due to vector meson exchange. The potential is approximated by a static Yukawa potential and the kinematics is simplified. The actual physical masses of the particles are used so that SU3 symmetry is broken. The resulting problem reduces to a set of coupled channel Schrodinger equations which are solved exactly on a computer. The K matrix and the eigenphases are calculated. Several examples of virtual bound state resonances are found. The model yields a Yo 1405 as a virtual bound state of anti-KN and N 1510 as a virtual bound state of K Sigma. Author
