Proposal for the determination of the mesonic mean square radius of nucleons from « knock-on » pion production

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

A method is proposed to determine the mesonic m.s. radius of nucleons from the differential cross-section of « knock-on » pion production. The essence of the method consists in extrapolating the differential cross-section as a function in the nucleon recoil momentum to unphysical values. The size of the unphysical region decreases with increasing primary energy. Possible limitations of the method are discussed briefly.

Riassunto

Si propone un metodo per determinare dalla sezione d’urto differenziale nella produzione di pioni di « knock-on » il raggio quadratico medio mesonico dei nucleoni. Il metodo consiste essenzialmente nell’estrapolare sino a valori non fisici la sezione d’urto differenziale espressa in funzione del momento di rinculo del nucleone. L’estensione della regione non fisica decresce al crescere dell’energia primaria. Si discutono brevemente alcune possibili limitazioni del metodo.
