The result is negative, since Barkan \emph{et al}. (Rev. Sci. Instrum. 39(1), 101-104, 1968) have reported that a polarized neutron beam again splits up in a Stern-Gerlach apparatus after depolarization: this cannot possibly be explained by the above assumption of a constant scalar property. The conclusion is therefore that it is not possible that SQM emerges from any such model of the EPT, in which it is assumed (in addition to the axioms of the EPT) that the fundamental rest-mass-having components carry a constant scalar property but no vectorial property spin. This result can be generalized to all deterministic hidden-variable theories that include this assumption. CopyrightOpen access
