“…1(a-c), but we obtained results that share the discrepancy with experiment reported elsewhere [9][10][11][12][13][14][15]. We have since repeated these calculations using wave functions obtained from the Paris [16], Nijmegen [17], Bonn B [18] and RuhrPot [19] NN-interactions, but we obtain results that are essentially all the same and continue to show a collective discrepancy with experiment. We realize that in all but the most forward scattering angle data, such discrepancies cannot be explained by any uncertainty in experimental absolute scale.…”

We present pp-bremsstrahlung cross section calculations at the π-production threshold to search for kinematics that best differentiate model-dependent descriptions of the NN t-matrix and accentuate the contributions of isoscalar meson-exchange currents. Existing optimization procedures are shown to be completely unreliable due to the neglect of meson-exchange currents and phase space variations. We show that phase-space hides the most important differences in model t-matrices, but that improved data will be critical to further investigations of exchange currents.

“…Based on Yukawa's pioneer work, potentials for NN forces mediated by the exchange of boson fields with masses below 1 GeV were invented and successfully applied to various problems in medium energy nuclear physics [1]. Despite of their remarkable ability to account for quantitative details of NN phenomenology, none of these models contains any reference to Quantum Chromodynamics QCD, which is believed to be the underlying microscopic theory of the strong interaction.…”

The notion of interacting elementary particles for low and medium energy nuclear physics is associated with definitions of potential operators which, inserted into a Lippmann-Schwinger equation, yield the scattering phase shifts and observables. In principle, this potential carries the rich substructure consisting of quarks and gluons and thus may be deduced from some microscopic model. In this spirit we propose a boson exchange potential from a nonlinear quantum field theory. Essentially, the meson propagators and form factors of conventional models are replaced by amplitudes derived from the dynamics of self-interacting mesons in terms of solitary fields. Contrary to deduction, we position the inversion approach. Using Gel'fand-Levitan and Marchenko inversion we compute local, energy-independent potentials from experimental phase shifts for various partial waves. Both potential models give excellent results for on-shell NN scattering data. In the off-shell domain we study both potential models in (p, pγ) Bremsstrahlung, elastic nucleon-nucleus scattering and triton binding energy calculations. It remains surprising that for * Contribution to the International Conference on Inverse and Algebraic Quantum Scattering Theory, Lake Balaton '96.
