  The one solitary boson exchange potential (OSBEP) is used to evaluate
observables of NN elastic scattering below pion threshold. In this approach, we
use a nonlinear model of self-interacting mesons as a substitution for the
commonly used phenomenological form factors. NN data support an empirical
scaling law between the pion and other meson fields, which suggests a link to
QCD and significantly reduces the number of parameters in the boson exchange
potential. The analysis of np and pp observables distinguishes the model by its
fit and few adjustable parameters. An outlook to apply OSBEP in pi-N systems is
given.
