The full Bonn potential, combined with a relativistic quark-gluon annihilation potential, is compared with recent {ital N{bar N}} polarization data from LEAR and with measured differential cross sections (elastic and charge exchange) below {ital p}{sub lab}=800 MeV/{ital c}. It is demonstrated within this approach that a careful analysis of {ital p{bar p}}{r arrow}{ital p{bar p}}(EL) and {ital p{bar p}}{r arrow}{ital n{bar n}}(CEX), at the same energy, in terms of the five independent helicity amplitudes can be used to selectively test specific boson exchange contributions to {ital N{bar N}} scattering. The charge-exchange differential cross section in forward direction is particularly sensitive to the one-pion-exchange potential in this model. This feature could be used to see if recent attempts to fit {ital NN} data with a much softer {pi}{ital NN} form factor can be made compatible with {ital N{bar N}} data.
