A Direct Photoelectric Determination of Planck's "h"

Quantum theory was not originally developed for the sake of photoelectric phenomena. It was solely a theory to the mechanism of absorption and emission of electromagnetic by resonators of atomic or subatomic dimensions. It had nothing to say about the energy of an escaping electron or about the under which such an electron could make its escape, and up this day the form of the theory developed by its author has not been to account satisfactorily for the photoelectric facts presented herewith. are confronted, however, by the astonishing situation that facts were correctly and exactly predicted nine years ago by a form quantum theory which has now been pretty generally abandoned.
