Here's a reference to a conference session I just found on the Web. The presenters claim that prior demonstrations of the A-B effect were bogus, produced by the magnetic field of the moving particle interacting directly with the adjacent magnetic field. It also states that no evidence of a magnetic vector potential acting on a particle in the absence of a magnetic field has ever been demonstrated. Any comments? ----- Session K19 - Magnetic Modeling II. MIXED session, Wednesday afternoon, March 19 Room 2206, Conv. Center [K19.04] Ehrenberg-Siday-Aharonov-Bohm (ESAB) Effect Has Not Been Observed Gordon R. Freeman, Larry D. Coulson (University of Alberta) The beautiful results from two types of experiment that were claimed to confirm the existence of the (misnamed) Aharonov-Bohm Effect, with coherent electrons in split beams (Tonomura amp; co.) and split conductors (Webb amp; co.), are explained quantitatively by the energy of interaction of the magnetic field produced by the moving electrons with the magnetic flux of the adjacent applied field. The electron velocities (and phases) change by opposite amounts in the two parts of the split beam, and de Broglie wave interference occurs in the rejoined beam. No effect of a magnetic vector potential in the absence of a magnetic field has been demonstrated, so the ESAB Effect has not been demonstrated to exist. -- Sponsor the DES Analytic Crack Project http://www.cyberspace.org/~enoch/crakfaq.html
