An Erratum to this article was published on 01 July 1956

Summary

The pion annihilation of antiproton-nucleon pairs in boundS-states (singlet and triplet) are analyzed taking into account conservation law and selection rules previously founded. With a statistical model for the valutation of transition matrix elements the ratio of three pion to two pion annihilation is calculated and, for the 3π annihilation, the angular distributions and energy spectrum of the final mesons. Finally some considerations are done about the annihilation of the pair from isotopic spin eigenstates.

Riassunto

Si studia l’annichilamento, in due e in tre mesoni π, di coppie antiprotone-nucleone in statoS (singoletto e tripletto). Con un modello di tipo statistico per il calcolo degli elementi di matrice per le transizioni, si valuta la relazione tra le sezioni d’urto per annichilamento in due e tre mesoni, e per quest’ultimo caso si ricavano le distribuzioni angolari e gli spettri energetici. Nel calcolo si tengono in conto le leggi di conservazione e le regole di selezione previamente trovate. Infine si fanno alcune considerazioni sulla possibilité di annichilamento di coppie in autostati dello spin isotopico.
