Abstract：
Using the precise expression of electron,positron distribution function we obtained earlier,we derive the rigorous analytical expression of radiator in e⁺e^－ collision process.This series expression converges rapidly to the precise result required.The comparison with existing approximate expression is also given.Our result benefits the precice calculation for the radiative corrections in e⁺e^－ collision processess.
