Summary
It is demonstrated that the form factor fitting the electronproton scattering data, which could formerly be described by an exponential density distribution, can also be given entirely equivalently by one of several cut-off proton models. Such models have a theoretically desirable asymptotic behaviour, according to present ideas of field theory.
Riassunto
Si dimostra che il fattore di forma che soddisfa i dati dello scattering elettroneprotone, che precedentemente poteva essere descritto da una distribuzione esponenziale di densità, puó essere espresso in modo del tutto equivalente da uno dei molti modelli con cut-off protonico. Tali modelli hanno un comportamento asintotico teoricamente desiderabile secondo le idee attuali sulla teoria di campo.
