Summary
The principle of charge-independence coupled with the unitarity and time-reversibility of the scattering matrix enables one to express the production amplitude of the K−-capture reactions in terms of the scattering phases of the final state interaction. By making impulse type approximation, certain relations between K−+d and K−+2N absorption cross-sections are obtained. The experimental data have been analysed on the basis of the global symmetry of strong interactions. It is found thatwithin the limits of our approximation this symmetry is incompatible with the experimental observations.
Riassunto
Il principio di indipendenza dalla carica associato alla unitarietà e reversibilità nel tempo della matrice di scattering permette di esprimere l’ampiezza di produzione delle reazioni di cattura K− in termini delle fasi di scattering delle interazioni finali di stato. Applicando approssimazioni del tipo dell’impulso, si ottengono alcune relazioni fra le sezioni trasversali di assorbimento K−+d e K−+2N. I dati sperimentali sono stati analizzati sulla base della simmetria globale delle interazioni forti. Si trova cheentro i limiti della nostra approssimazione questa simmetria è incompatibile con le osservazioni sperimentali.
