Summary
By use of a modified Fubini-Furlan technique, it has been shown that a certain commutation relation among spatially integrated currents gives the low-energy Kroll-Ruderman theorem on the photo-production of a pion by nucleon.
Riassunto
Con l’uso di una tecnica di Fubini-Furlan modificata si dimostra che una certa relazione di commutazione fra correnti spazialmente integrate dà il teorema di Krall-Ruderman di bassa energia sulla fotoproduzione di un pione su un nucleone.
