Summary
The peratization method of Feinberg and Pais has been applied to the lepton-nucleon interactions, examining possible effects of the nucléon vertex structure. In this case, the correction to the coupling constant, due to the contribution of the ladder graphs at zero momentum transfer, is different, in general, from what obtained in the pure leptonic case.
Riassunto
Il metodo di« peratizzazione » di Feinberg e Pais è stato applioato alle interazioni tra leptoni e nucleoni, esaminando possibili effetti della struttura del vertice nucleonico. In tal caso, il contributo dei grafici a scala a momento trasferito nullo dà una correzione alia costante d’accoppiamento che è diversa, in générale, da quella che si ottiene per le interazioni puramente leptoniche.
