Abstract
We describe an experiment to test a quantum-like theory which predicts quan tum-like behavior for an ensemble of electrons in a classical configuration with static magnetic and electric fields. Some of the earlier experiments had supporting evidence for anomalous, quantum-like effects in such a situa tion showing systematic modulations of electron current when a retarding po tential is varied, even though the quantum wavelength of the electrons in s uch a configuration was less than a billionth of the spatial width of the p otential well. Our experiment conclusively rules out any nonclassical, quan tum-like behavior in electron transmission through simple electric barriers , when magnetic fields are present. We identify secondary electrons generat ed at various electrodes as the main source of apparent anomalous behavior. We also present a classical derivation of the quantum-like equation descri bing the modulations.
