Confirmation of action constant for bremsstrahlung.

A new action constant for bremsstrahlung has been derived and published by the author. This paper provides experimental confirmation of that action constant by measurements of the intensity of bremsstrahlung from pure metal elements. Such measurements must be taken under the condition that essentially all of the kinetic energy of an incident electron is converted into the energy of an emergent photon. The dependence of the intensity on the exponent of the atomic number, Z, of the target element (measured to be 4/3) shows that the new constant is valid.
