Abstract
A procedure is described for extracting the pole position of a resonant amplitude from a knowledge of the phase shift versus energy. Pole positions are determined for the four -wave resonances in the nucleon- system with high precision. The use of the pole position to define the mass of unstable nuclear states is discussed.
