A Search for the de Broglie Particle Internal Clock by Means of Electron Channeling

Abstract: The particle internal clock conjectured by de Broglie in 1924 was investigated in a channeling experiment using a beam of ∼80 MeV electrons aligned along the 110 direction of a 1 μm thick silicon crystal. Some of the electrons undergo a rosette motion, in which they interact with a single atomic row. When the electron energy is finely varied, the rate of electron transmission at 0°shows a 8% dip within 0.5% of the resonance energy, 80.874 MeV, for which the frequency of atomic collisions matches the electron's… Show more

“…Together with the Compton wave length, it sets a unified spacetime Compton scale that limits the wave packets width in space and time before negative energy and negative time components (particle and antiparticle) occur significantly. Moreover, it supports the existence of an internal property, the de Broglie clock with a period τ 0 = h/m 0 c 2 [25,26,27].…”

“…If non periodic systems or similarly systems with periodicities larger than our observation time are interacting with the elementary system we are measuring, its periodic evolution will be no more manifest. 21 Time has been defined by counting the number of oscillations of the Cesium atom or of the incense lamp of the Pisa Dome, the number of the orbits of the Earth or of the Moon. But these definitions inevitably make use of the a priori assumption of periodicity of isolated elementary systems and, "by the principle of sufficient reason", we assume that the whole information of these elementary systems is encoded in a single period, as implicitly said by Einstein himself [1] in his definition of a relativistic clock.…”

“…A hypothetic boson with the mass of an electron has an intrinsic rest periodicity, proportional to the Compton wave length, of about 10 −20 s. Even for a mass as light as that, the periodic dynamics are extremely fast. For instance, the oscillation period of the Cs-133 atom, which is used in the operative definition of time, is of the order of 10 −10 s. Remarkably, this intrinsic periodicity of massive particles has been indirectly observed only in a recent experiment [21] for electrons (which for the scope of this paper can be though of as fields with antiperiodic T t ).…”

“…It has now been demonstrated that zitterbewegung corresponds to a physical periodic oscillation in the substructure of an electron (Cattilon et al, 2008). It has also been shown analytically that a closed-loop electromagnetic wave construct could account for the characteristics of spin, magnetic moment and static charge as measured in an electron Elementary sub-atomic particles (Williamson and van der Mark, 1997).…”
