Query: Skyrme-Model $\pi NN$ Form Factor and Nucleon-Nucleon Interaction   We apply the strong $\pi NN$ form factor, which emerges from the Skyrme
model, in the two-nucleon system using a one-boson-exchange (OBE) model for the
nucleon-nucleon (NN) interaction. Deuteron properties and phase parameters of
NN scattering are reproduced well. In contrast to the form factor of monopole
shape that is traditionally used in OBE models, the Skyrme form factor leaves
low momentum transfers essentially unaffected while it suppresses the
high-momentum region strongly. It turns out that this behavior is very
appropriate for models of the NN interaction and makes possible to use a soft
pion form factor in the NN system. As a consequence, the $\pi N$ and the $NN$
systems can be described using the same soft $\pi NN$ form factor, which is
impossible with the monopole.
