In quantum electrodynamics, Bhabha scattering is the electron-positron scattering process:
There are two leading-order Feynman diagrams contributing to this interaction: an annihilation process and a scattering process. The Bhabha scattering rate is used as a luminosity monitor in electron-positron colliders.
Bhabha scattering is named after the Indian physicist Homi J. Bhabha.

Famous quotes containing the word scattering:
“What was he doing, the great god Pan,
Down in the reeds by the river?
Spreading ruin and scattering ban,
Splashing and paddling with hoofs of a goat,
And breaking the golden lilies afloat
With the dragon-fly on the river.”
—Elizabeth Barrett Browning (1806–1861)
