On a possible way to detect de Broglie's waves

According to de Broglie an atomic system results from the association of a localized object and an extended ondulatory phenomenon interacting through the quantum potential. A natural developement of this picture implies the existence of new effects in the superposition of incoherent waves, for example in neutron interferometric experiments.1.
