Summary
In order to avoid the well known paradox of Einstein, Podolsky and Rosen, some modifications can be introduced in quantum mechanics, along lines pioneered by Furry. These modifications obviously have to be tested experimentally. Some time ago, Bohm and Aharonov claimed that an experiment of Wu and Shaknov (on the correlation of polarizations of annihilation photons) can be considered as an empirical proof against the Furry hypothesis. However, a careful analysis of the properties of photons shows that they are not suitable to formulate the paradox of Einstein, Podolsky and Rosen, so that the argument of Bohm and Aharonov against the Furry hypothesis is not valid. Some other possible experimental tests are proposed.
Riassunto
Allo scopo di evitare il ben noto paradosso di Einstein, Podolsky e Rosen, si possono introdurre alcune modifiche alla meccanica quantistica, seguendo la via indicata da Furry. Queste modifiche ovviamente devono essere controllate sperimentalmente. Qualche tempo fa Bohm e Aharonov affermarono che un esperimento di Wu e Shaknov (sulla correlazione della polarizzazione dei fotoni di annichilazione) può essere considerato una prova sperimentale a sfavore dell’ipotesi di Furry. Invece un’analisi accurata delle proprietà dei fotoni mostra che non sono convenienti per una formulazione del paradosso di Einstein, Podolsky e Rosen, cosicchè la tesi di Bohm ed Abaronov contro l’ipotesi di Furry non è valida. Si propongono altre possibili prove sperimentali.
