Summary
The cross-section for π- production in the reaction γ+p → p+π++π- has been measured at photon energies between 600 and 850 MeV. The experimenbal results agree with the existence of an isobar of the nucleon of energy lower than that expected of theD 13.
Riassunto
É stata misurata la sezione d’urto di produzione di π- mediante la relazione γ+p→p+π++ π- ad energie del fotone oomprese tra 600 ed 850MeV. I risultati sperimeutali sono in acoordo con l’esistenza di un isobaro del nucleone di energia minore di quella prevista per la D19.
