Abstract
An experimental test has been made of DuBridge's theory of the distribution of normal energies of photoelectrons. With a modified parallel-plate method of analysis, photoelectrons were ejected from a strip of Mo foil which could be held at any desired temperature. Current-voltage curves for temperatures from 300° to 965°K show a good agreement with the theory. From the shifts required to fit the experimental and theoretical curves the values of Vmax at 0°K can be determined. For any fixed temperature these values of Vm fit the Einstein equation, and for a fixed wave-length they are independent of T, as required by the theory.
