A Way of Modeling Radiation-Matter Interaction

摘要

In this paper we review the celebrated experiments of Einstein-de Haas and Zeeman for the charge/mass ratio determination, which are usually explained in the framework of quantum mechanics in terms of conservation of the total angular momentum of radiation and matter by means of the selection rules. We essay to show that both experiments are amenable to alternative explanations that dissent from quantum mechanics, as long as we are willing to distinguish between a "signal" and its "transduction". We also recall that the transduction effect for the Einstein-de Haas experiment has been reproduced under controlled conditions in autopilots. We propose that, whenever a generic transduction phenomenon, which in general is non linear, can be reproduced in a controlled fashion, such controlled reproduction is considered an "explanation" of the radiation-matter interaction that results in the given phenomenon.
