“…Fortunately, there exist by now abundant data of pp and np scattering permitting a model independent partial wave analysis going up to T max LAB = 3GeV [32], i.e. p max CM = 1.2GeV allowing a direct reconstruction of scattering amplitudes [33][34][35] from complete sets of experiments. In general, phase shifts can only be considered observables when a complete set of measurements (differential cross sections, polarization asymmetries, etc.)…”

The repulsive short distance core is one of the main paradigms of nuclear physics which even seems confirmed by QCD lattice calculations. On the other hand nuclear potentials at short distances are motivated by high energy behavior where inelasticities play an important role. We analyze NN interactions up to 3 GeV in terms of simple coarse grained complex and energy dependent interactions. We discuss two possible and conflicting scenarios which share the common feature of a vanishing wave function at the core location in the particular case of Swaves. We find that the optical potential with a repulsive core exhibits a strong energy dependence whereas the optical potential with the structural core is characterized by a rather adiabatic energy dependence which allows to treat inelasticity perturbatively. We discuss the possible implications for nuclear structure calculations of both alternatives.

“…More good data on neutron-proton scattering are clearly needed, possibly with the aim of directly reconstructing the isosinglet amplitudes. This is particulary promising in the forward direction [2] but the conditions are almost as favourable for backward pn → np scattering (often loosely called the np charge-exchange region) and it is this which we want to consider in some detail in this paper.…”

The existing experimental data on the d(n, p)nn and d(p, n)pp cross sections in the forward direction are reviewed in terms of the Dean sum rule. It is shown that the measurement of the ratio of the charge exchange on the deuteron to that on the proton might, if taken together with other experimental data, allow a direct construction of the np → np scattering amplitude in the backward direction with few ambiguities.
