In this study, the cross section , of the interaction i i e e ; (i , )was calculated .The effect of the weak mixing angle 2 sin w on the cross section , of the same reaction in the energy field89GeV S 94GeV was also studied. The effect of the center mass energy s on the cross section , was also studiedfor two boundary values of the weak mixing angle 2 sin w : 0.23221 , 0.2233. The study showed that the effect of the weak mixing angle on the sectional difference , (nb) gets in the energy field s (911)GeV , and takes a maximum value almost equal to the mass of the Z- boson .
