    Results on the cross section for the production of electron pairs in pp collisions at x/~--630 GeV are presented. The measured value is a= 405 + 51 (syst.) _+ 84 (syst.) pb, in the invariant mass interval 10 < m < 70 GeV. The results are compared to recent theoretical calculations which include O(o~ 2 ) QCD contributions. The comparison of these data with those of lower energy experiments show approximate scaling as a function of the variable x/z= m/x~ss
