Reflection of Electrons by Standing Light Waves: Experimental Study

“…In some early experiments [12][13][14][15] attempts were made to measure the deflection offree electrons due to a light wave. Two experiments reported an effect 12,13 , while two others did not 14,15 .…”

“…The early experiments [2][3][4] only observed some electron recoil in a standing laser wave, but did not confirm the predicted electron scattering, which should obey Bragg's law. The deep splitting of photoelectron angular distributions in standing-wave multiphoton ionization (MPI) observed by Bucksbaum et al [5] was the only evidence supporting KD's conjecture.…”

By applying a nonperturbative quantum electrodynamic theory, we study ponderomotive resonances when an electron beam is scattered by a standing photon wave. Our study shows that the ponderomotive parameter u p , the ponderomotive energy per laser-photon energy, for each of the two traveling laser modes possesses a minimum value ω/(m e c 2 ). Ponderomotive resonances occur only when the ratio of the laser photon energy to the electron rest-mass energy is a fraction, where the denominator is twice the square of a positive integer and the numerator is the total ponderomotive number, which is also a positive integer.

“…Since then, several experiments have been made to verify this effect, but all have failed [13,14]. However, the diffraction of atoms passing through standing wave laser field was verified [15][16][17].…”

The present theory of atom optics is established mainly on the Schrödinger equations or the matrix mechanics equation. The authors present a new theoretical formulation of atom optics: Feynman's path integral theory. Its advantage is that one can describe the diffraction and interference of atoms passing through slits (or grating), apertures, and standing wave laser field in Earth's gravitational field by using a type of wave function and calculation is simple. For this reason, we derive the wave functions of particles in the following configurations: single slit (and slit with the van der Waals interaction), double slit, N slit, rectangular aperture, circular aperture, the Mach-Zehndertype interferometer, the interferometer with the Raman beams, the Sagnac effect, the Aharonov-Casher effect, the Kapitza-Dirac diffraction effect, and the Aharonov-Bohm effect. The authors give a wave function of the state of particles on the screen in abovementioned configurations. Our formulas show good agreement with present experimental measurements.
