THE PHYSICAL REVIEW A QUANTUM THEORY OF THE SCATTERING OF X-RAYS BY LIGHT ELEMENTS BY ARTHUR H. COMPTON The title and intro of Compton's paper reads: ABSTRACT A quantum theory of the scattering of X-rays and y-rays by light elements. -The hypothesis is suggested that when an X-ray quantum is scattered it spends all of its energy and momentum upon some particular electron. This electron in turn scatters the ray in some definite direction. The change in momentum of the X-ray quantum due to the change in its direction of propagation results in a recoil of the scattering electron. The energy in the scattered auantum is thus less than the…

    Many physicists remained skeptical. But Arthur Compton’s 1923 explanation of X-rays scattering off electrons was near-incontrovertible evidence that quanta were real.
