Summary
In a previous article we have suggested the experiment ofWu-Shaknov on the annihilation radiation of positronium as a test for the paradox of Einstein, Podolsky and Rosen. In this article, we answer certain criticisms of our conclusions, raised byPeres andSinger. These criticisms are shown to be erroneous, being based on an incorrect interpretation of the polarization of electromagnetic radiation in the quantum domain.
Riassunto
In un lavoro precedente abbiamo suggerito come prova per il paradosso di Einstein, Podolsky e Rosen, l’esperimento diWu-Shaknov sulla radiazione di annichilazione del positronio. In questo articolo rispondiamo ad alcune critiche alle nostre conclusioni, avanzate daPeres eSinger. Si mostra come queste critiche siano erronee, essendo basate su una scorretta interpretazione della polarizzazione della radiazione elettromagnetica nel dominio quantistico.

Peres andSinger begin this section with a statement that we « have overlooked the important fact that the polarization of photons is physically different from the spin of fermions, as photons have zero at mass, their spin… is always oriented in the direction of propagation. » Since we have never attempted to formulate the paradox of E.P.R. by considering directly the spin operator of photons, the above statement has no connection with our article, and is indeed quite irrevelant to the point at issue.
