In the Klein-Nishina formula, the square of this value is multiplied by one half the square of the Compton radius and a polynomial involving Cos theta and ratios of photon energies.
In the Klein-Nishina formula, the square of this value is multiplied by one half the square of the Compton radius and a polynomial involving Cos theta and ratios of photon energies. The Rydberg constant is equal to the square of this value multiplied by the mass of the electron times c, all divided by four pi h-bar, and the Lamb shift is proportional to the fifth power of this quantity. One method of calculating this quantity involves setting the Lande (*) g-factor equal to a polynomial in this value, while applying perturbation theory to QED results in power series in terms of this quantity, which was originally posited as the ratio of the velocity of an electron in the Bohr model to the speed of light. At high energies this value would diverge at the Landau pole. Also defined as e squared over h bar c, for 10 points, name this coupling constant for the electromagnetic force, which Arthur Eddington posited to be equal to exactly one over 137.
