"WebThe cross section dσ=dk⊥ for the γ −P=R-fusion processes gradually increases and reaches a maximum at k⊥ ≃0.25 GeV. The purely dif-fractive CEP fusion processes, R− −P and O−P,give much smaller cross sections there. For the photon brems-strahlung, discussed in [2], the cross section for k⊥ → 0 diverges as 1=k⊥.
