The incompleteness of the Schrodinger equation in classical limit

The Schrodinger equation with the nonlinear term is derived in the framework of the Dirac heuristics. The particle behaves classically in case the mass of it is infinite. The nonlinear term is crucial and involves new physical constant b. The constant can be measured by the same methods that were used in the case of the Casimir effect (Spaarnay, 1958; Tabor et al., 1969). Of course, the experimental procedure is based on well educated experimenters. The new experiments, different from the Zeilinger ones, are proposed, with Faraday simplicity, for the determination of this new very small constant b. The article is the extended and perfectionized version of the articles by author (Pardy, 1993; 1994; 2001).
