Abstract
Experimental results on pion-nucleon scattering near threshold are analysed in terms of a potential interaction. Radii and depths are presented and discussed in the square-well approximation. It turns out that extrapolation of theP 11-amplitude at negative energies is consistent with a bound state showing the properties of the well-known nucleon state.
