Experimental observation compatible with the particle internal clock in a channeling experiment

An experimental observation compatible with the particle internal clock in a channeling experiment was conducted. The particle internal clock can be an observable quantity only if the wave function is slightly modified. The main momentum resonance may be 162 MeV/c instead of 81 MeV/c, since a dispersion of the electron trajectory is sensitive to the absolute value of the wave function amplitude, which has twice the frequency. In order to design the experimental set-up by means of a Monte-Carlo calculation, a phenomenological model of the electron's motion and internal clock was used on the basis of classical mechanics. The event rate at crystal tilt angle was studied as a function of the electron's momentum. The results show that this rate is constant except in a sharp momentum range of the order of 1% centered at the resonance momentum. The data of the crystal tilt angle analysis shows the usual rosette motion feature.
