Determination of dirac’s neutron form factor from electroproduction of pions

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

An isobaric model for photoproduction is now extended to the virtual photon in the case of electroproduction of pions from protons. Numerical results are obtained and discussed in comparison with available data. It is shown that one might not hope to extract the pion form factor, but that the electric form factorF n1 should be negative or equivalently thatF nch is negative.

Riassunto

Si estende qui, nel caso di elettroproduzione di pioni da protoni, al fotone virtuale un modello isobarico della fotoproduzione. Si ottengono dei risultati numerici e si discutono confrontandoli coi dati sperimentali disponibili. Si dimostra che non si può sperare di ricavare il fattore di forma del pione, ma che il fattore di forma elettricoF n1 deve essere negativo o, equivalentemente, cheF nch è negativo.
