Summary

The experimental results of the proton-proton collisions at 1.5 GeV and 2.75 GeV by Fowleret al. are analysed in a phenomenological way. It is found then that the partial waves ofl = 2/5 and Z= 2 / 7 are mainly responsible for the pion production at1.5 GeV and 2.75 GeV respectively. Further, from our analysis in such an energy region it is shown that the effective size of the proton is nearly constant ((0.6/0.7).10-3cm).

Riassunto

Si esaminano sotto l’aspetto fenomenologico i risultati ottenuti da Fowleret al. sulle coilisioni protone-protone a 1.5 GeV e 2.75 GeV. Si trova così che le onde parziali con l=2/5 e l=2/7 sono le cause prevalenti della produzione di pioni a 1.5 GeV, rispettivamente a 2.75 GeV. Dalla nostra analisi risulta, inoltre, che in questo intervallo di energia le dimensioni effettive del protone sono pressochè costanti ((0.6/0.7) .10-13 cm).
