Summary
The spectral functions of the electromagnetic form factors of the nucleon are discussed within the framework of the static theory. 1/M recoil corrections are also included and it is shown that these corrections are close to those given by dispersion theory and that they profoundly alter the spectral functions indicating that the application of the static model to this problem is of doubtful validity.
Riassunto
Le funzioni spettrali dei fattori di forma del nucleone si discutono nel quadro della teoria statica. Si includono anche correzioni per il rinculo 1/M e si mostra che tali correzioni sono prossime a quelle date dalla teoria dispersiva e che alterano profondamente le funzioni spettrali indicando che l’applicazione del modello statico a questo problema è di dubbia validità.
