AbstractThe first negative parity state of the nucleon resonance N(1535) is predominantly described as an eta-nucleon (skyrmion) bound state, which subsequently couples to the pion-nucleon system. Solving the two channel problem approximately, it is shown how bound state properties are improved to describe the nature of the resonance.
