= Angular Correlation of Electron Positron Annihilation Radiation
{wiki=Angular_Correlation_of_Electron_Positron_Annihilation_Radiation}
Angular correlation in the context of electron-positron annihilation refers to the angular distribution of the gamma radiation produced when an electron and its antiparticle, the positron, annihilate each other. When an electron and positron collide, they can annihilate to produce gamma-ray photons. Typically, this process produces two gamma rays (photons) that travel in opposite directions.
