Abstract
The large value of the effective total cross-section on nucleons of the three-pion system with 0− quantum numbers, experimentally found from the analysis of coherent nuclear product when the 3π mass is 1.1 GeV, is explained as due to the simulation by a one step model of a more complicated mechanism, containing as essential ingredient the interference with an intermediate 1+ channel. The model allows us to extract information on the transition 0−-1+.
