Distorted-Wave one-pion-exchange model for inelastic proton-proton scattering

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

The one-pion-exchange model, modified to allow for initial-and final-state interactions, is applied to those inelastic two-body proton-proton scattering processes involving the excitation of the two lightest nucleon isobars. The model apparently overestimates theN *+ (1238) production cross-section, but gives a satisfactory account ofN *+ (1430) production.

Riassunto

Si applica il modello a scambio di un pione, modificato per tener conto delle interazioni nello stato iniziale e nello stato finale, a quei processi di scattering protone-protone a due corpi inelastici che coinvolgono l’eccitazione dei due più leggeri isobari del nucleone. Il modello apparentemente sovrastima la sezione d’urto di produzione delN *+ (1238), ma rende conto in modo soddisfacente della produzione delN *+ (1430).
