The name of Arthur Holly Compton (1892–1962), American physicist, used attrib. or in the possessive of certain phenomena in Physics, as Compton effect, the scattering and increase in wavelength of an X-ray (or gamma-ray) photon on encountering an electron, with a partial transference of energy from the photon to the electron; Compton shift, the difference between the wavelengths of incident and scattered photons; also Compton absorption, Compton electron, etc.

XXVI. 282 The ratio of intensity of the Compton lines. 1932Discovery Oct. 337/2 When these photons encounter solid matter, they will generally experience slight scattering due to Compton encounters with the planetary electrons of the atoms. 1934H. L. Brose tr. Sommerfeld's Atomic Struct. (ed. 3) I. i. 49 In comparison with the photo-electrons,..the ‘Compton electrons’ have a considerably smaller value. Ibid. 50 The Compton effect demonstrates very impressively the dual nature of radiation. 1955W. Heisenberg in W. Pauli Niels Bohr 13 Bothe and Geiger showed experimentally by means of the Compton effect that the energy conservation law is valid for individual processes also. 1955L.
